I went to the thrift store and stumbled upon the McQueen body. At first I was going to buy it to add scenery to my track. Then I thought, why not make it into the body of my RC!? I looked it up on YT and behold, you did it! Going to do this soon, thanks for posting.
They are "Louise T-Rocket 1/8 Truggy Soft". (Louise = Duratrax in some areas) Looks great and handles good. Only concern is they are little bit soft on the side walls, so dont know how durable they will be in the long run :)
