" ----------------------------- " " [] " The rear axle is an AMC 15, -stock- rear. he says the po swapped an amc20 - probably from a mj - in, and a v8 too. " but D35 gears are supposed to fit. i was told this by randy's ring and pinion some years ago. " The side gears in the diff that the axle slides into may be different " due to different axle diameters and/or splines, but the ring and " pinion should interchange. i was also told that splines are the same [27], but the d35 was converted to c-clip halfshaft retention early on, so d35 side gears have a divot for the clip that amc15s don't. d35 diffs swap into amc15s, giving us a fine assortment of l/s types, but axle shafts and wheel bearings are different. iirc pinion bearings and seal are the same. btw early d35s have a square amc20 axle housing bolt pattern but c-clip d35s have a mopar pattern. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
