I've got bunch of non running ( 37,42, 46, 51 and 59 )chevy pickups. see photos:

I want to get the 46 running again. Someone did a poor job of putting in a 307 V8 and a 350 tran, who knows what 5 bolt rear end and some cut up 5 bolt front hubs. I want to make it look mostly origional but I'm not going to overdo it with exact year matches. Will the 51 or 59 frames fit without serious modification? The frame on it was cut up by the prior hot rodder. I would like to use the 59 because of the external drive shaft.

Does anyone have comparison specs on the changes to the half or 3 quarter ton frames?
