Here is how I look at it. If the clutch was still good simply get a 10.5 or 11 inch 26 spline disk and remove enough or the hub to clear the pilot bushing. Both sizes work with the pressure plate. Not all hubs are the same some may only need a little bit removed some more. You can get a disk and new throw out bearing for about 80.00 bucks. You can also get a pilot bearing that has the same ID and OD but is .125 thinner this usually is enough on these gmc flywheels for most disks. Sorry I did not respond to your pm but it is hard for me to encourage the use of these POS transmissions. Barry
