Mine came from mid '70s dodge and ford trucks I believe. They came in lots of different vehicles over a wide range of year models. Got lucky w/ the one from the dodge truck...it had 3.54 gears and the stronger powerlock differential. Install new bearings, cut the housing and weld on the pass. car ends, new 35 spline axles and 35 spline side gears from Dr. Diff, and put it in the car.

The new rears have definitely gotten more expensive. Back in 2003 or 2004, I paid $1750 for the Moser 60 that's in my cuda. No brakes, 35 spline spool and axles w/ long studs, 4.10 street gear, billet 1350 yoke, chrome cover. Been beating the snout out of it ever since and only took the cover off one time to change the fluid after 10 years.
