Billy Weeks makes some excellent bodies. Don't think he has a website but you can get in touch with him on his myspace page or www.imdra.com. The willys pro mod body I got from his is flawless. I think he has pro stock and funny car bods now as well. Went to one of those mud drags the other day. Not quite as soft as what you are describing. Sand Dragging is gaining popularity around here. There is a group in Dallas that has built an R/C sand drag track and there are others from what I've been told. I love to go to the sand drags. Nothing like big V8 power and 200 ft of ROOST Haven't gotten any video of the R/C dirt draggers yet but here are a couple of the big boys going at it in Llano Tx.
