Check the Firebird and Camaro 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.
NO
As far as a direct fit, the 82-92 Firebird/Camaro is the same generation. Any from these years should be a direct bolt in.
Yes
The 2010 Camaro can fit up to 4 people but if you have larger people in the front seats then I would say only small children will fit in the back seats. Larger people would be defined as over 6' and 200lbs.
