It might be a little pricey but get a machine shop to make a mount for you. Just take some measurements and they can draft it for you. Presicion is key when making a motor mount.

I luckily have a roommate that can draft like the devil. My mount did cost $65, but is worth it in quality.

Hey and leave losi alone! I loved mine until I decided to start running 3S lipos in it, BUT the drivetrain still held up. Even after I tested it in the grass. The power was just to much and would just make the truck undriveable. I like the added weight and 4wd of the MT2 way better. It doesn't just wheelie uncontrollably. Sure it also makes it a little slower but who needs a 55mph ST anyways ;) Heres a pic because Im such a pic wh***.
