41 chevy truck frame

[2lazy2p]

I purchased a 1941 Chevy truck cab and front clip but did not recieve a frame. What frame would fit this cab. I was thinking 70/71 but am being told they are too wide. I set it on a s10 frame but getting the front wheels in the wheel wells puts the radiator right next to engine (had to remove fan) which means I am going to have to reposition the engine . Please addvise, I have a 1941 chevy sedan frame and a 1950 3600 frame both stripped to rails but would rather buy a rolling chaisis from a junk yard that would be more modern than the ones I have.

Thanks any help is apprieciated
