Sorry I meant to answer your PM, but I didn't find the body you were talking about until just now. If that body is still available then that's the one you want to try. It's one number off of the original but it's your best shot.
Are you still running the stock rear shock tower? It only has one spot to hold the body on. The replacement one is a generic one. It will fit the NXT or XXX-NT also I believe. Something like that. So keep that in mind when looking for a new body. Hopefully the body you're looking at will work with either.
The original rims were still available not long ago. I had the original ones that came with mine and I just used those for goofing around. But I bought a brand new set with my racing tires on them. Here's a pic of the old ones.

Those alway held up the best on the track, because some people just can't drive and push you into everything. But I also had several sets of HPI rims that worked fine as well. I had some dirt hogs and a set of paddles for the sand hill out back. They also have some with a wider offsets to help with the high speed rollovers. Hehe. They have adapters that come with them. Take the truck and bearings with you and make sure they work before you leave the store.
Hope that helps some.
