Camaro067

i just picked up a pair of 91-92 style z/28 hood blisters, but i'm not sure if they are GM or aftermarket. i was hoping someone could tell me what the part numbers for the GM blisters are supposed to be, so i can figure out what i have. thanks

I dont see a part number on the bottom but heres a picture of stock GM blisters. I had bought these before i realized they had to go on a Z28 hood and not a Flat hood. I ended up selling them and getting after market ones from Hawks, which don't have the tabs around the bolts, the bolts are fiberglassed right into the blister.

Hope this helps...

i can see where there are numbers/letters cast into both of these but i cant tell what they say, some near the front some on the back, my blisters look almost identical to these, could someone take a minute and measure the length, width of the front and width of the back? that would tell me if mine are the same as factory or if mine is wider, otherwise i dont know how to tell. i dont have the correct Z hood yet to try to fit it, just a late 80's IROC hood. thanks

I may be wrong... but from posts that I've read before.. will the stock blisters fit on a late 80's iroc hood? I think they may, but again, i'm not sure, my hoods flat, well, was!
