Since the cars are so old it ends up being a matter of choice..
I like having both... my Bowmint has Pontiac on the valve covers
mine say pontiac,and i have aircleaner decal too.so i have it all screwed up,and accually i dont care.in most vases cars aren't nice enough that it really matters,id rather have a nicer car with incorrect decals.im board.cheetah,i coukd use some 327 275 hp decals if you have a set,im so confused
