folks im still in need of help with this clutch.The problem is when we got the truck it was all apart.it came with 3 different clutch discs .There was a 10" 11" and a 12" that we found in the bed.so far we have figured out that the 10" that classicparts and jim carter carry ,will not fit, the preasure plate is to small,its not lining up with the bolt holes.did 54 chevy pickups with 235 come with 11" clutch discs?we think the correct one that will work is a 11".thanks folks any help wouls be appreciated. john
