67/68 Camaro rear seats?

[Blaster11]

Are 67/68 Camaro rear seats the same except for the upholstery? The reason I am asking is I want to use Marquez door panels in my 68 Firebird but the seats between Firebirds and Camaro's are different and will need to be changed and I may have found a rear seat from a 67 Camaro for a good price.

Thanks,

Bruce
