I have identified the problem!My reverse input drum is the second style with the round feed hole.
Next step is placing that drum into the scrap bin and purchasing a new AC Delco rev input drum. Your current belleville plate, piston, return spring and clutch pack w/backing plate will all transfer over. That should solve your clearance problems and enable you to install an Alto wide red band vs the stock band.
Also, verify you dont have first design rev input clutches - those were thicker than all of the subsequent clutch designs and used a waved plate instead of a belleville plate. They were only found in the first design drums w/the steel piston.
