Well on that truck that I got son of seed truck LOL I confirmed 1 and 3/4 drive shaft turns per one wheel turn so it's a 354 open. Job said he was interested in the housing and the Axel's so maybe the 354 gears would work for you? I wouldn't know how to ship this thing what a mess..
so 3.55's. That's a nice gear. With a 904, I'm not sure I want to go more than 3.23's on the street. If you were closer, I'd buy them off you "just to have them". LOL.
To ship the rear end housing, you need to strap it to a pallet, then take it to fastener.
I was thinking this morning...... about going a lot faster. Found a set of 4.11's, sure grip in a 741 case for sale. Then a 9.5 converter..... solid cam (I already have adjustable rockers), ……….. but then I end up with a 1 purpose car again... just what I got away from…..
