Ofcourse they can! Something from a Firebird would be easy. You can buy seat brackets for aftermarket seats so I am sure you can get a set of brackets that go on several kinds of seats.

Actually the seats will fit inside the camaro but you wont have any seat belts. The seat belts in a coupe are mounted in the roof and the seat belts in a convertible are mounted on the sides of the seats. so the seat will fit but you will have to buy some seat belts or use your old ones. The back seats should have no problems tho. I have a 2002 Camaro.
Camaro car seats?
