The homologated 1972 Bathurst lightened flywheel (19lb) part number 9929634









According to the late LJ Nasco Parts Catalogue, the homologated 1972 Bathurst lightened flywheel, part number 9929634, never made production until JP386598, the very last batch of the fire breathing 1973 Bathurst XU-1,s. Some say this last batch of 150/151 fire breathing 1973 Bathurst XU-1,s were and will all ways remain the ULTIMATE FINALE for the XU-1 Torana.

Sorry to drag this thread up again but i need your help and honest opions !!!!!!!!!

For those that have the Vin Disc could you count how many XU-1,s were built between :

L193821 to L195055 (Adelaide)

H221242 to H222921 (Brisbane)

These are the cars built in the months of January and February 1972 with Australian ADR,s of 1/72 and 2/72.

According to the Vin Disc how many cars were built in the months of January and February ????????????

Thanks........

[meanmachine72]

bructer

can confirm bazzas count for brisbane 128 or 129

the extra one was maybe built on 21/12/71...first LJ xu-1???? in late 1971??

of to count adelaide now

[meanmachine72]

i have counted the adelaide cars 4 times now and i keep coming up with 68
i have found 4 gtrs betsbac 76203E0 with JP motors in them
L194151...JP 103031
L194153... no details
L194461...JP 103455
L194595...JP 104774
I reckon these are actually XU-1s with the wrong betsbac number logged against them
there were no other grts built during this period so counting these as xu-1s i come up with 72 adelaide cars
and the brisbane count 128 or 129

the extra one from brisbane was maybe built on 21/12/71...first LJ xu-1???? in late 1971??


hey bazza did you count those gtrs as xu-1s to???
cheers johnno

Hi johnno

Yes - we have counted them as XU-1s since the beginning. It makes sense because they are part of XU-1 batches and the JP numbers fit in with numbers within the batches.

I notice that the 'orphan' XU-1 is dealer 239 which is GMH internal.

Of note these 4 GTR,s also have the XU-1 diff ratio (E = 3.36). In this time frame (January & February) there were no other GTR,s being built only XU-1,s. Under the C.A.M.S. Rules Holden were required to build 200 cars to be eligibile to race the 1972 LJ GTR XU-1. So in your opinions is it a safe bet to assume these 4 GTR,s are in fact XU-1,s ???

Thanks for the help guys............

hello anthony,welcome to forum mate...good to see you chime in on this

The 1972 Bathurst Special LJ XU-1 came with Factory Fitted Sprintmasters,thats how you tell if your Aug-Sept 1972 LJ XU-1 is one of the Bathurst Specials,it should have the Factory Fitted Sprintmasters on it,im sure they are stamped on the Back of the Sprintmaster the date when made with dots and a 72 on them,so if you havent got them Sprintys on them,be abit hard to tell.
The Sprintmaster were ok on the 10/8/1972 by C.A.M.S, So after that date the Sprintys would of been put on the 72 LJ XU-1 Cars,i think the Sprintmasters on the 1972 Bathurst Specials are 6 Dots with a 72, Fly might know How many Dots there is i think its 6 Dots.

[meanmachine72]

yes... give scotty (UFO XU1) a pm there as good as NOS ones

Hi Al,

Mine were fitted with the original sprinty's from the factory.
But the the original owner didn't what them,so the original nibbles,
rims were fitted on,they are still there today,and it still has the,
the original wheel spacers there is 10 of them,3 on each front wheels,
and two on each back wheels,and the date on the nibbless rims,
are 6/72 on all five of the nibbless rims.

Cheers John.

Well the Sprintmasters are Dated Stamped 6/1972 on the Aug-Sept 1972 Bathurst LJ XU-1 with the factory fitted Sprinty's.
Im Guessing your Car is a Aug-Sept 1972 LJ XU-1, Least you have 6/72 Nibless Rims
You would think there might be a few Aug-Sept 72 XU-1's that Dont have there factory fitted Sprintmaters.
10/8/1972 Date is the C.A.M.S ok date for the Sprintys,so the First 72 LJ XU-1 with Factory Fitted Sprintmasters would not be far off that date. ?????????

[xu2308]

So going off C.A.M.S Date of 10/8/1972 When Sprintmasters were given the OK,
Count 200 1972-LJ XU-1's built starting from the 10/8/1972, and that should be the 200 Bathurst Specials.
Harry Firth told me the 200 - 1972 LJ XU-1's that got the Self Locating Factory Fitted Sprintmasters are the 200 Bathurst Specials, so it would have to be the 200 Cars Built after C.A.M.S gave the ok on the 10/8/1972.
Well thats how it should work out,unless Holden Slipped Factory Fitted Sprintmasters on 1972 LJ XU-1's before the C.A.M.S date of 10/8/1972.

Hi Al,

From January to the end of July 1972 Holden built a total of 600 LJ XU-1,s (According to the vin disk) with the required minimum needed in this time frame being 600 (According to the CAMS rules & CAMS homologation paperwork).

200 required for Eligibility H2-3 (Jan, Feb)
200 required for Homologation 3/3V (Mar, Apr, mid May)
200 required for Homologation 1/1V (mid May, Jun, July)


Eligibility H2-3, 200 required


Homologation 3/3V, 200 required


Homologation 1/1V, 200 required

Hi Fly

Have been reading this thread with much interest.
Does anyone know what an ERRATA is?
It's an error sheet, which basically means that Holden supplied CAMS with incorrect specifications and ERRATA 3/3V rectifies the matter. In this case it refers to items 2 & 3 on the original Homoligation H2-3 Dated 3rd February 1972.
Would Holden have really produced 200 cars to satisfy an error?

Cheers
Dave.

hi xu2 308 i know of a 9/72 xu1 its a genuine bathurst it still has the original broadcast sheet with the code for the sprintmasters and the rest of the package they come out with, so i wouldnt be putting my money on the first 200 cars built after the 10/8/72 thats a big call in what u are saying

my 2 bobs worth

regards aldo

Well after the 10/8/1972 you would think 200 cars after that would still fit in 9/1972 cars Aldo,and the 10/8/1972 is the date that C.A.M.S gave the ok for the sprintmasters.
Harry told me the 200 Cars that were fitted with the Self Locating Factory Fitted Sprintmasters are the 200 Bathurst Cars,so going off C.A.M.S date of 10/8/1972 you would think thats when the 200 Cars were Fitted with the Sprintmasters on that date or just after.
Harry says on the Chevron HDT DVD as well about the 200 Bathurst XU-1's were fitted with the Sprintmasters,it all depends when Holden put the Sprintmasters on the Aug 1972 LJ XU-1's but i say the 10/8/1972 would be a good starting point to look at,only way to know is to find a Aug 72 LJ XU-1 Owner with a Broadcast Sheet that has the Sprintys on it,that is before 10/8/1972 to say that theory is wrong,but thats what i be looking at,i might be wrong but as the 72 Bathurst Specials came with Factory Sprintmasters,its a good guide i think

Hey Guys

I believe you will find if you read the homologation sheets, GMH built the cars then applied to CAMS for recognition.
eg: In the case of the first batch of LJ XU1s, 200 identical cars were produced between 19 January 1972 and 3rd February 1972.
It was only after the production of the first 200 identical cars that GMH submitted the homologation forms to CAMS.
I believe the 200 '72 XU1's fitted with the sprintmaster wheels were produced prior to 10/08/1972.

It would also figure that the ammendment for the springs, lightend flywheel, XJ cam and other bits dated 29 August 1972 would mean that XU1's built up to that date had those parts, or if the 200 cars with the sprintmasters were sent to Dandenong to be fitted with the other parts then they had only 19 days to retrofit those cars. Most likely that as the cars rolled off the production line they would have been shipped off to Dandenong to be fitted out. That way they wouldn't have to do 200 cars in 19 days.

It appears that the homologation forms were really not much more than a formality, but obviously a vital part of being allowed to compete in CAMS sanctioned motor sport events.

G/Day Dave
I have thought many times about this myself. According to the vin disc Holden produced the 200 cars required. A more accurate description is that Homologation 3/3V rectifies the matter. Homologation 3/3V being an entity by itself. If Holden could get away without building 200 cars because the homologation simply had the word errata on it would,nt all of the homologations had errata on them. OOps sorry those 200 1/72 & 2/72 XU-1,s we built should of had detroit lockers in them and should have been fitted with sprintmasters also. Plus we gave you the wrong cam specs and the flywheel should be a 19lb lightened one etc etc etc.......... C.A.M.S. were,nt fools, they made the rules and had to be followed to a T or risk disquailification. Holden tended to follow the rules to a T while Crysler and Ford appeared to do everything in there powers to flaunt them.
In reguards to any 8/72 or 9/72 LJ XU-1 being sent to Dandenong to get parts fitted is just pure rubbish and would suggest to you to take very little notice of what is written in the Fiv Antoniou book as its pure rubbish........... Can you honestly see Holden sending 200 cars from their Brisbane and Adelaide plants to Melbourne to get fitted with bits ? Plus the fact that under the C.A.M.S. Rules these parts were not required to be fitted in production only that 200 basically identical units be built.
It appears to me Dave you have done some research yourself and have a good understanding of the changes and requirements. Lets not let the Fiv Antoniou book get in the way of the truth though ok.............
