Power steering questions

I am talking to a fellow who wants to add Bendix power steering to his
57 Golden Hawk.  I recon the linkage stuff will fit and the pump will
bolt to the engine using later stuff, but what about the crankshaft
pulley?  Will the one used for the Saginaw pump line up with the later
Bendix pump?  Anyone done all this before?  I don't want to sell him
parts he can't use; he already has the pump, ram, valve with pitman
arm and steering box (Ross box) from what I can tell by the pics he
sent me.  Also, will the later bellcrank work?  Supercharger is still
there.
