Yes I am aware of the Pontiac difference..I have a 64 bonneville convertible from Kentucky....Got it ten years ago it has been in storage inside since 1970....Rust free needs restored....389 hi-po garnet red with black top and matching red leather interior...

In Canada the pontiacs used the Chevrolet engines...and they had models that were chevy's with pontiac badging...Such as the Canso acadian(66 chevy II nova) and the Beaumont (Chevelle)

My dad has an auto salvage and I grew up pulling fenders and doors off mostly 60's cars in the yard....They are all gone now crushed they got so rusty....

Down here in SC the rain kills the 50's cars....It rains so much that when the window rubbers dry out water gets into the floor pans and trunk pans and rusts them out from the inside out

I junk 2-3 cars a month...Mostly 4 doors and rusted 2 door cars....I am an addict...My wife says I need to go into car rehab
