Thanks for the replies and info. So far I have mounted the motor. I made and mounted a battery tray as well. Waiting for my extended chassis before I continue. I designed the battery tray to mount using the exisiting holes so the brushless parts can be removed and the truggy can be converted back nitro if desired. Here are some pictures of the project so far.

With the battery mounted on it's side the body easily clears.
