<BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content"> Rear is definitely 1.876" 30 spline, my size chart shows the front as 1.438" 30 spline, but that maybe wrong as that is the same size as the 8.875" RG pinion.

My info. shows same for front and rear Phil. 00457108 P/G inner; 09417781 P/G outer; 11505123 Brg, Diff 2ea. However it does list different yoke kits: 12479139 rear; 12479137 front.
