I have a drill/tap guide setup for threading the crankshaft that's available for loan if you're interested. The crankshaft center bolt size is 7/16-20, same as a small block V-8. Drop me a pm if you're interested in the tooling. I believe the puller holes in the damper are 3/8-16, but I'll be glad to confirm that in the morning when there's some light in the storage shed.
