Dave, The Warden and I go back a little bit starting with me almost making him put an M117 or M110 oil filter in his 300D.

TW, the EPC says that the 85 D and SD have different diff unit part numbers but the same diff case part number. That tells me that it should be a physical match. Question is, will 126 axles fit a 123 diff? The EPC isn't clear about how the axles fit into the diff. The 123 section shows axles that press into the diff, the 126 section shows a flange that goes into the diff and the inboard CV joint bolts to the flange. However, the 123 and 126 have the same diff side gear part number so the splines must be the same even if the rest of the axles are different. Confused? I am.
