Numbers are G345 and I cannot find this sequence on the decoding chart. | | | | | Joined: Feb 2004 Posts: 29,771 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,771 | How many bolts does the rear cover have, is it oval, round or odd-shaped? Can the ring and pinion carrier assembly be unbolted from the front of the housing? Dana-Spicer axle assemblies like the Type 44 or Type 60 have a roughly triangular-shaped rear cover and the carrier is not removable from the front. Can you post some pictures?
