Good deal, does the engine run?
It wouldn't be that hard to convert it. The simple way is to cut off the stubs & attach the new axle to the underside of the frame. Keep in mind, though, that this could raise the back end a few inches, which shouldn't really be a problem, unless you do it properly. Can you weld?
yes the engine is solid he told me he maybe has 15 hours on it. it was on a water pump. and as for the welding no i have never welded but want to learn. but i can get a buddy from a machine shop to weld it for me. whats a good welder to start off??
