RPM made a full chassis conversion kit for the RC10T/RC10 a few years ago, it consisted of a chassis with front and rear braces to eliminate flex, front/rear bulkhead, all hubs, steering arms, wishbones, arm mounts, battery strap, shock towers, front bumper, basically thing that was plastic was made of their near unbreakable nylon stuff.
Its discontuned now, although when I spoke with them a few days ago they confirmed most of the parts are still around, because they have a limited lifetime warranty against breakage.
Couple of pics of mine (from the auction, it looks like it could do with a good rebuild):

I've already constructed a lexan plate to relocate the servo similar to how I've done it in my T2, which will allow for 8-9 cells to be fitted on the chassis. Only minor modifications to the car are required.
The other car in the photo is another T2 which I'm going to rebuild to check its all good and put back on ebay. Anyone in the UK here that wants one is welcome to make me an offer also :)
