My name is Troy JOhnson and I'm new to the forum. I have an 88 iroc with the 700r4 trans and am going to install a m21 4 speed. Can anyone tell me what the corredt flywheel is and where is the plade to get the cheapest one and stock is ok with me. Will the truck motors from the same area have the same bolt pattern etc? Will appreciate any help Tks.........Troy
