Well see you have a problem, some 87 fiero's have internally balenced flywheels some dont, if yours is a early 87 or late 86 on the date made its probably not going to be internally ballenced if yours is late 87 or mid 87 it probably is, best way to find out is when you pull out your engine, check and see if a weight is welded to it, if it is, then you need to get a flywheel without the weight or remove the weight thats on it, Go to the nearest gm dealer near you and order a flywheel for a 1993-1995 camaro 3.4L it is for the internally balenced engine, or if yours is a dual overhead cam 3.4 then get a flywheel for a 1991-1994 lumina z34 5 speed
im pretty sure im right, correct me if im wrong anyone, but i do know the 3.4's are internally balanced so make sure you get the flywheel thats right.
