One of my boys could do it for you cheaper than any shop.... if he wants too..
LT4 clutches will work fine... thats what im using. I would only recommend the LT1 clutch, LT4 clutch, SLP clutch with their flywheel, and McCleod. But you wont have the cash for a McCleod. All the others use the LT4 pressure plate and design their disks themselves.
I would not resurface that flywheel again.. if its been done once then u need a new one. Some people say its ok if its only been shimmed x hundreth of an inch but i wouldnt do it.
