According to the 1986 TDM 201.122 with a 5 speed manual transmission came with a 717.410 (GL 68/20 A-5) tranny and the 3.23 differential up to October 1985 and a 717.411 (GL 68/20 B-5) and the 3.91 differential starting in November 1985.

No lip on this diff. That area of the diff is so small I dont think you could stamp anything on there, more of a ridge. The 300d has a large lip on each side with the ratio on the right one.

The other info is very good to know. The 190 diff looks smaller in size to the 300d... maybe I am crazy. I do like that 3.91 ratio though. We will have to wait and see how it comes together.

I will get some basic pics when I get home to the camera.

Thanks
