I am doing a automatic to manual conversion on my 87 Fiero V6 and I did buy a 4sp Clutch Arm from them for the conversion. The part number was 64120 from their catalog. That is the V6 - 4speed Clutch Arm. The part that is currently listed on their site, 64300 is for the 4cylinder 5-Speed. I am not sure if it is how the Clutch Arm is bent that makes it incompatible or if is something else. You might want to check back with them from time to time. I currently do not see 64120 listed on their site.
