I have 2, used, 28 spline, 9" posi drop out centers, 2:75 ratio's for $275 each and 1, used, 31 spline, non posi with 3:50 gears, some pitting on teeth but will not effect preformance, ready to install, for $200. The posi units are out of a 76 LTD, and the other out of a 78 T Bird. I did not drive those cars, so I do not know if the clutches are good or not. The posi units teeth look excellent, no pits, chips, or cracks. The posi hubs have been inspected and are crack free! Shipping would be extra, alone each they are $50 with insure, packaged nicely. I would sell all 3 as a package deal for $700 + shipping. Need more info, let me know, pics if wanted.
