Here's the tutorial on how to make it.
I started with JB welding some of the old bolt holes
I then drilled holes for the transmission
Countersinking the holes
You can add and subtract washers to adjust the anti-squad (caster angle)
File down the taps in the rear of the chassis and cut off some material.
Sand down servo holes, don't do as much as I did, I would just shave off enough to fit the servo horn.
skipped ahead a bit here, just mounted the rear trans, and made the front steering brackets, I made a diagram, but it's completely wrong, I need to make a new one. Also made a top plate, it's the original top plate but I filed the lines off it and cut it down.
Here are the diagrams of the rear, front, and steering. You can use the physical pictures and these as references
The steering rack is right, just the angles measurements are wrong.
Hopefully this is enough, if you need any more pictures just ask and I will take some more
