My feeling is that for this thing to be totally bulletproof it needs a one piece mount for the motor which is attached to/the same as the diff mount. Having a two piece design is asking for trouble. I WISH I had the access to machines to build something like this but I can imagine a lower center diff mount- machined - which had a motor mount on the side of it. As it is now, I'm not 100% sure that I can get the motor and center diff on exactly the same horizontal plane. I'm confident that someone out there has the skills. Funny thing, with all the people converting 1/8th vehicles. I'll be whatever R&D someone invests in making a somewhat universal diff mount/motor mount will be repaid many times over by offering it for sale. Think about it.
