Got the headers off my old 79 chevy monster still lying around and after being stuck on older chevys for awhile I ended up with a 90 model. Now on my 3rd 90s model chevy, and want the headers on it. Will they fit in the frame? Just looking under the hood it seems the frame is closer together on a 90s truck compared to a 80s. Seeing as the exhaust is rusted on my truck, if I removed them T_T it's a do or die deal they have to fit or I'm screwed for a bit lol.
