This is a Smiling Ray's (http://smilinrays.webs.com/slotcarbodies.htm), resin body I've had a while. Its pretty straightforward, I only pulled the exhausts from a Carrera Vintage NASCAR chassis and cut them off square, drilled them out and remounted them right back where they came from. The chassis trimmed very nicely for the body, and there was lots of room for mounting posts inside.
