Looking great Dale, I'm really enjoying this build.
The Gardner Camaro didn't have the wedged nose. I believe that was an old 1967 Bill Brown car, a very early Trans-Am car before they started wedging the noses.
But the Penske Camaros definitely had it done in 1968 and '69. Here is one of the 1968 Penske Camaros pictured in 1970 with then owner Craig Murray. I believe they took a slice out of the radiator support panel and then tilted all the front sheet metal forward, then repaired the rear section of the front fenders so it didn't show.
You can see in this shot the huge gap at the top rear of the panel where it doesn't meet up. I assume the panel was replaced at some stage but not modified correctly.
