SOLD SOLD SOLD I have a rare 392 Hemi Crank Hub from Orday Speed Shop. Anodized aluminum on a hardened steel hub. 1-1/2” ID with 1/4” keyway. The six 3/8 mounting bolts are on a 2.782” bolt circle with a 2” register. I believe this works on 4-71 to 16-71 superchargers. It has the slightest ding on the aluminum but very nice otherwise. Orday Speed Equipment was owned by **** Crawford who was known for his work with the development of the Donovan 417 engine.
