Yes I have a MY6 or A833 with OD in it. I can throw that in the truck with the 3.90 59 pumpkin that I have. Should work good.
I also have a 60's suburban rear with posi 3.54 gears and 6 lug. It's perfect width for the 47 to 54 1/2 ton's.
I just wanted to know what trans. would go with that rear. It can not use the original 3 speed because it is an open rear.
I think I will sell that rear and also an SM 420 trans. I have sitting here too.
Thanks everyone.
