I just pulled a Detroit stamped 70883 from my Ford 9". I've owned the rig for 6yrs now and would say the detroit has seen maybe 5k miles on it of which 99% was street. Unit looks good and has 4.10s bolted to it if you'd care for both. Seller $275 or I'd trade for a fully done Bronco for my wife :) Can text/e-mail pics. Live on the NW side of Colo Spgs.
thanks
