Re:
ok Rampage, this was simple...US made so everything is imperial
Drive side arm/spindle has an internal diameter of 1/2" or 12.7 mm. Outer diameter is 3/4" or 19.05 mm.
Non-drive side arm with the pinch bolt will need an internal diameter of 1/2" or 12.7 mm to slide into the hollow spindle, and outer diameter of 1" or 25.4 mm to catch the outside of the splines sleeve and hold everything in place.
FYI - i found out that these are 1974/75 1st Gen Bullseye prototypes made in a very small batch just for testing. By 1976 all cranks were made with spindles that were 7/8" or the now famous (or infamous) 22.225 mm. These do not have the hole in the spindle for the safety key like other early 1st Gen Bullseye cranks. So the keeper is a must i'd say.
Let me know how much to PayPal and where to send it to. Thanks again!
