To hold the bearing at the rear diff, the engine plate is so long to cover all 4 posts. You have to cut the two posts in the front, where formerly the motor was tied down, they should be the same height as the rear posts.
So the metal plate, which is bent in the front to hold the 180, elongs till the rear bearing to hold it down.
So the shaft has 3 bearings!!!
After this modification, you can use any 130 (S01, S03, Yeah, ...) or any 180 (GPM, HPI, or even the HPI modified with 30t).
