Im in love with the 'mongo' rims...I gotta keep mine. I'll make way with the tall gears. OR-Perhaps I'll get lucky when I open mine up, and have a gift from the Chevy gods.

It is understandable pre-interstate...who would ever need more than 55mph? Ive restored some early Brit bikes with 3 and 4 speed gearboxes...45mph tops! which is still about 10 mph faster than they safely handled. Prior to tapered roller bearings, these headsets made for a nasty wobble at speed.
