Pics always help lol.Do you have the plastic spacer between the chassis and diff mounts? Also the diff. gets flipped doing the e-conversion.Are you using the metal 45 tooth spur or plastic spur? "some guys did have to make the plastic gear a little thinner in early conversion kits"
I believe it is a earlier mount. And yes it is a plastic spur. I was wondering if this might be it as well. I remember people having similar problems with the early mounts. Frustrating...lol.
