Possible trans upgrade

[Vetruck]

Also- Why is your R129 diff cover different in the rear mount bracket and holes then the one I show in the link? I would not think my current diff cover would interchange onto it since I have a small case, but I have never held either in my hands to even know. I am starting to think a trip to a MB bone yard is in order in the very near future before I continue this conversation.

I swear my head is hurting trying to find reliable facts on the internet. Wish I knew these cars better like I know GM stuff.

Then I think there is the issue of the vehicle speed sensor and ABS. I will have to have that recalibrated also so the speedo functions correctly (Again I am assuming?)
