Hi smiley.

You said "Neither have a part number embossed on them so that then makes either set the right ones for a set of sprinty`s "

I didn't say that they didn't have a part number, I said that they didn't have a PO (production option) number. Numbers like L20, M40, P06 etc these are PO numbers. A GM-H part no. looks like 7412345.

The whole point of this post is that the world map cap are NOT strictly correct for Spintmaster alloys on a '72 Bathurst LJ XU-1.

Sounds like your practising for the XU-1 nationals Dr Terry ?

Hi Simley,

I am in the same boat as you, I have a 4/73 bris car and have world caps on my sprints which came with the car from new?? Whats the deal then...were they available on both bris and ad built cars in 73??

Hi Guys.

I should reword that then.

The Sprintmasters were only fitted, as a mandatory item, to the 200 or so '72 Bathurst XU-1s, so GM-H could race with then under CAMS rules. The Sprintmaster wheels with the plain cap are a genuine GM-H part (with GM-H part numbers) & a dealer could then buy then in thru the spare parts dept & fit them as a genuine 'Nasco' accessory to any 6 cyl LJ after the initial 200 cars.

If you have the Sprintmasters with 'world map' caps, on the car from new, they were not supplied thru GM-H to the dealer, they were supplied by the local tyre shop who was a 'Globe' dealer to the GM-H dealer, as these are retailed by that shop as 'Globe' brand alloys not genuine GM-H parts.

If you have a 4/73 LJ with Sprintmasters that have world map caps, they did not come thru the GM-H parts network.

They were a popular aftermarket accessory at that time.

Hi Mondie.

You can't use the word 'all' or 'every' when dealing with homologation specials like Bathurst XU-1s. I'm not sure of the exact total number of these cars that were actually produced, but GM-H only had to provide paperwork to CAMS to prove that at least 200 cars were fitted with those wheels, before sale. So, most likely there were more that 200 cars fitted with those wheels, but how many more.

But, the fact is that these were the only cars that were 'required' to be sold with those wheels.

AFAIK all XU-1s were assembled at the factory with 5.5" steel wheels.

Hi Guys.

doublin gtr's comment illustrates why this is such a 'grey' area.

AFAIK all LJ XU-1s were fitted at the factory with 5.5" nibless steel rims & ALL their build sheets should reflect this. The Sprintmasters do not have a PO (production option) number because they weren't fitted in production. But they were fitted before they reached the selling dealers yard. They were fitted in the storage/transport yard at the factory or in some cases at the transport company's holding yard. I have heard of instances where the cars arrived at the dealers & had the Sprintmasters fitted by them using wheels supplied with the car, but this would be a very fiddly way of doing things & equally difficult to verify. Remember they (GM-H) had to make sure that 200 sets of Sprintmasters were fitted before Bathurst (& Sandown ??) that year. The steel wheels removed would've been returned to the factory & then fitted to normal production XU-1s on the line, to contain costs.

Having said all of this, the main point of this whole post is, would a '73 XU-1 with Sprintmasters be judged as being correct (or not) for concourse. In my opinion Sprintmasters (with the correct casting etc) are 100% OK on ANY LJ XU-1.

Have I opened another can of worms, or finally answered the question.
