1972 Chevelle Convertible Modern Rear Seat - help needed

[MBH]

Hello, looking for some comfort in the chevelle. Been lurking on here was thinking m4 front seats but after reading a thread that went out the window. Then I saw GTO seats and Camaro seats being the best bet, some people even getting the rears to work. It seems they so had coupes. I’m wondering had anyone with a convertible done this swap? Or if anyone is knowledgeable enough to help me figure out if it’ll work. I’ve read the coupe and convertible have different sized rear seats, thank you in advance.
