I am looking for a new Meritor U-joint assy merc part number 862129A 1. This part was superceded by 865425A03, a GKN assembly, I am looking for the Meritor version.

It is early.. Can't remember which is which, I believe you are talking about the old style XR input shaft with the large Ujoints.
Caps measure 1.328". If so I have one. PM me.

I found a post from 2010 about an old input shaft from an old XR Meritor style I also need one of those. Any leads???? Thanks. Mitch

Yeah that's the measurement. You have the whole assembly or just the coupler end and how much you want. Mitch. 508-400-7999
