No one has made any mention of this -  rear guard wheel arch lips are wider/ deeper than the front guard wheel arch lips .

[FLY_AGAIN_XU-1]

True, still 90 degrees on Adelaide built cars ? ? ? ?

 

Are yours at 90 degrees Kockum ?

Majority of front guard wheel arch lip is 90 , the section above the top of tyre is not .

Yep still original guards on front. In fact this car is very very original. Just checked the lips are 90deg or whatever normal cars are, just like your photos. I'm getting confused? Mines a May 72 so can't be a Bathurst anyway from everything I've read?

The panels were all pressed in the same tooling so they were all the same when they arrived at the VAPs.

That sounds right , may I ask you Dave if your 73 Brisbane beast has full 90 degree rear wheel arch lips and for the front guard lips mostly 90 like mine are ?

You are right Dave, the angle of the front wheel arch inner flange becomes acute at the top of the arch. GTR & S/SL front guards are the same.

 

My rear arch flanges are pretty much 90 deg but my front arch flanges are rolled up because I once tried to run 225/60/13 tyres on the front.

Thanks for the info Dave , mine had skinny Michelins when I got it in the seventies and have only had skinnies since , so I am confident that both front and rear wheel arch lips are how it left Brisbane .

Brisbane built cars had the front guards tapped down ( as pictured ) they also had the inner guards rolled to remove any sharp edges. Adelaide built cars did not...........

not to sure this is correct in regards to (front of guards been taped down Brisbane built ) i have now seen 3 x10/70 lc xu1 brisbane with only passenger side taped down any clarification would be great as i am due for paint and have gone with one guard only

Possible coincidence that all three have had the drivers front guard replaced?

C.A.M.S regs for Group C allow for minor fettling of guards in that era, just what is "minor" I suppose was very much open to interpretation  during this period of racing. My XU1 which is September 1972 build and ran in racing during this period has similar treatment to what you have described and has had no objections raised on recent examination for Group C / Heritage cars log book continuations. A car recently sold nearby and very much the real original deal did not have these lips massaged from new, however my car is known to be in the very first small run of the "1973" spec and was earmarked for race use from day one. It might be a case of a little like A Moffs  thin glass and alloy door panels 'ex factory that have only just been fessed up to perhaps?

My LJ Xu-1 is a September bulit car also,I have the same rolled rear lips as yours caterham,and my front guards are the same too,original front guards,and you all read what I wrote up in June 2007,that xu-1 Rat put up again.
I asked peter brock at muscle car masters at eastern creek in august 2006,of what he knew about the rolled lips on the guards,as I was doing a lot of research back then on my car,reading books as many as I could find.
Peter Brock told me that day,I have a race prepared car,he called them track packs ,the only is missing in my car is the roll cage.
I wrote and filled up a 50 page note book,of peter telling me about my car and what too look for and found everything that I wrote down,
I was blown away,he also looked at and showed me other things I never knew about it,and answered and my questions I had for him of my car,was very greatful of his help that day.
