Do you know the width of the rearend for a 1940 chevy 1/2 ton? Also, it seems everyone is putting an S-10 5 speed in their trucks, doesn't anyone put an automatic it them?

Do your own measuring, and don't take my word as "law". A 1940 should have a box that is 48.5 inches wide. It also has about 11 inches of fender on each side. Using rims that are 7 inches wide, with 4 inches of backspacing should center you up pretty well in the wheel well. A maximum tire size would be about 10 inches wide...lets say a 255 series tire. Can't garrentee that you won't have any rub anywhere, so like I said take your own measurements and do your own math. I don't have my rear in the truck or the tires, or the box to see if it all does fit.

However many have done it. The issue is adding the cooling for the trans. I have seen custom rads, aftermarket heat exchangers, and a trany cooler bolted in front of the Radiator.
