I have a '49 3600 that I am convering to 1/2 tom running gear to be able to put disc brakes on the truck. I have a friend who is giving me a 10 bolt with 3.42's in it. I really like the old granny low 4 speeds. Is it possible/hard to convert the SM 420 to an open driveshaft to match up with the 10 bolt?


If you think you can't, you're right. If you think you can, you're right.
