Here's another interesting article I found, seems Terry put in an official protest against one Allan Moffat driving the one and only famous Coke Trans-Am Mustang.
It was in the December 1969 Racing Car News
TOURING CARS
Controversy Rages Over Trans-Am
Is it or isn't it a touring car? This is the question CAMS are asking now that an official protest has been lodged by Terry Allan against Allan Moffat's Trans-Am Mustang. It seems that CAMS accepted the homologation papers for the car but the Rule 3(g) states that all wheels must be interchangeable AND the rear wheels on the Mustang will to fit on the front!!! Where do we go from here? As far as I can see most of them are illegal anyway, so why worry!!
One thinks Mr Moffat would not have been amused....!!
It would be interesting to ask Allan Moffat what he can recall about racing against Terry and the Big Block Camaro, Does anyone out there know Allan enough to ask the question?
