I have never seen a crank bracket on a AD. Have I missed something? Also, I don't think the ADs came with a crank. I do know they came with a jack and lug wrench. In my 53 restoration packet, there is no mention of a crank! I think the indent at the bottom of the radiator and the provision for a crank at the harmonic balancer is just a carryover from the ART DECO days.
