I scored a nice running '41 engine and I am planning on shoehorning it into my A frame. I'm locating a F1 crossmember to hold up the '39 trans. My question is can I get away with using the stock A rearend or should I use that old '47 rear I've got stashed? the engine is stock and I was gonna convert it to juice brakes anyway. Thanks guys for all youre input!
