Jeff's 727 rebuild thread
Ok Jeff. I like to see between 0.012 - 0.015 per friction plate. That means if you have 4 frictions in there, you are looking for a clutch clearance of 0.048 - 0.060. If you have 5 in there then aim for 0.060 - 0.075. The large retaining ring is a selective. It is available in 6 different thickness to enable an accurate clutch end play setting. There are also thin frictions available in 0.061 thickness. Looking at your drum you will be able to get 5 thins in there.
