I responded to your PM Ben.
Yea the CEN stuff has wierd gearing in the diffs... I would do whatever you neeed to do to get rid of that Ferris Wheel 66T center gear. It screws up you gearing choices as well as pushing the battery way out to the side.
What I did was replace the front and rear diffs with the Hotbodies 43/10 truggy diffs and then the center spur gear with a normal 46T buggy spur gear. It was a good setup. I took out the spacers that CEN has under the center diff mount that raise it up to work with the stock 66T gear, then the RC-Monster Cen buggy motor mount will work with about a 1/2 or so spacers on the top so the upper chassis brace can bolt on in the stock position. I'm not sure about the exact size of that 1/2" spacer any more. You would have to measure the height of the spacer that goes under the center diff mount and get something the same height for the top of the mount. Not quite sure from memory, and I dont have it any more to measure anything.
You can kinda see what I did in this picture. Hope this helped and good luck on the conversion. Its a great truggy for the price and tough as nails.
