7.5" rear ends as well in 79-86.

 

79-85 Carbed with 7.5" rear ends
Early yearrs were either C4 autos or SROD 4 speeds.

Think it was 82 the 2.55 v8 was available and its a boat anchor of a motor.

85 was the first year I believe of the HO motor with forged pistons and roller cam.

86 was first year for EFI

79-86 also have 10" front brakes 87+ are 11"

87 front end designed and interior changed quite a bit. They went to e7 heads and forged pistons with valve reliefs, 60mm throttle bodys

86 were e6 heads with flat top pistons and 58mm throttle bodies

88 was first year for mass air for california cars

89 all cars were mass air

85 gt were rated at 215 or 205 hp, 86 gts were rated at 195. but had more torque due to fuel injection.

90 was first year of the air bag steering wheel

91 first year of pony rims and larger fenders to accomdate the larger 16" rims, it also got body color matched side mouldings, earlier years were black mouldings

91 they went to o ring style valve cover gaskets and a slightly different wiring harness

92 got better hatch striker bushing setup

93 got hyperautic pistons


some of thats probably wrong, but its close
