I've been doing my homework on the body mounts and the best that I can find are from the SC8, #89426. The posts are square on three sides and rounded on one side, shave it square.

Like it or not, Traxxas Invented the short course class twice with 2wd & 4x4, In doing so they set a standard. There are more than a hundred bodies available for it. there is no performance gained from moving a body hole 1/2 inch!

For me the fact that the SC10 4x4 works with my existing collection of Protrac wheels/tires, batteries, hv motor & mmp esc makes this truck a free upgrade when I sell off last seasons truck. Now the bodies can fit right on it too without punching a bunch of new holes. Heck, they had me at metric hardware. I love sharing as many parts and tools amongst as many of my RC's as possible.
