Well, I can't believe it! Someone found me a set of piston expanders! 320201. I also read my Glenn engine rebuilding manual, and now I understand how knurling, and the piston expanders work. They go in just under the oil ring, to expand the middle part of the piston where the cylinder is more tapered. Knurling works the same way. I have a couple of shops that I can call on Monday to see if they still knurl pistons.

Other than a few more inspections once I find out about the knurling, and some cleaning, I should ready for reassembly. All the parts are shipped!
