will the RC 8 buggy body fit on the RC10 GT?

No, and so you know, when people go out of their way to help you get a car in running order then you ask how much you could sell it for... the answers tend to stop there.
Get the RC10GT running and take a vid of it in action, they are a blast, then I'll set you up with a body that will fit.
You've come this far, just finish it up and have some fun with it instead of selling.

ok, i got the reciever mounted and the fuel lines ran. i had to buy a new exaust pipe and a new front bulkhead. i think ive got everything together on it, ran some cleaner thru the motor and put a new glow plug in it. my only problem right now is getting the carb/brake servo hooked up and functioning properly.

i looked on ebay and the condition that mine was in in that picture i wouldnt have gotten anything for it, not even the money i have into for new parts. i was trying to get some money to convert mmy other rc10gt to brushless and put a dirt oval modified body on it. that way i would have my brushlessGT and my brushless stampede. i have 2 complete rolling rc10gt's and building the third. just trying to get money to put into the other 2. sorry</p>
