I'm wanting to swap from power to manual steering. I'd like a rebuilt steering gear but I'm having trouble sourcing one other than Cardone and I've heard negative stuff about their quality. Also I've been totally unable to source a pitman arm, which I'm assuming is different from manual to power. Also....it looks like they used the same manual box way up into the late 70's at least. Anybody know the which other cars/years used the same box as the 300 in '66? I'm thinking maybe all C bodies were the same.
