Moser 9 inch diff with 6.20 gears and 40 spline spool. Through bolt housing. 10 bolt pinion. 1350 universal joint. No passes. Was installed in a gasser project I bought. Wrong gear for my set up, so it was swapped out with another Moser chunk. Can still see the set up dye on the ring gear. Was painted to look less obvious, otherwise it is as received from Moser. Buyer pays shipping.
