I posted a message a few days ago about my transmission that would not shift (grinding). In getting into the mechanics of the truck, I have found that my newly acquired "restored" truck needs most of the transmission gears replaced as well as the case. In addition the clutch facing, pressure and linkages need work. This work will be completed in the next few days. My question concerns the flywheel which from the looks of it was not turned during the "restoration". It is a 1962 engine. My mechanic thinks the flywheel can not be turned down more than 60 thousands without causing problems. Does this sound right? We of course don't know the history of this flywheel or how much material may have been removed over the years. Anyone know how thick this thing was to begin with? Anyone know where there might be a new one? Thanks
