I bought the big block hyd bell/used plate/disc etc from a guy & it will be going into my 65D100 that has a /6 hyd clutch 3 speed. The problem is that the NAPA guy cant find an app for anything other than a 318 and I don't know the year/app of the stuff I bought from the guy (& I forgot who). I think I will take the plate/disc in & go from there. The kid really tried over the phone but I think this calls for a hands on visual.
