The '42 is probably the closest fit.

The '51 or '59 front brakes can probably be adapted to the '46 front axle and the '59 rear axle is an easy swap to the '51 frame, but probably a little wide under a '46.

That's of course assuming they are all 1/2-ton frames, and you didn't say what they are...
