I need to know where a 82-92 camaro normally rusts? thanks Zac
the same places any 20+ year old car will rust, everywhere. The truck area under that huge window that probably leaks would be a good guess.
My brother had an 83 camaro back in the day and it was a complete rustbucket, you couldn’t put anything in the back as it would fall thru the floor. You could do a sweet flintstone impression thru the floorboards on the passenger side though. 
Passenger side floorpan near the firewall, the firewall under the heater box, fenders, rear quarters around the wheel lip, rad support. Basically check everything.
everywhere?
sometimes see them rusting in front yards, and every now and then on the edge of a treeline next to a house. all of those poor “project cars” get torn apart and then the rednecks can’t figure out how to put them back together.
