Historic Racing Miniatures did a beautiful 1/24 scale resin full kit, but they're expensive if you can find one.

I recently bought a Cox 1/24 slotcar to convert to a static model, but it'll need a scratchbuilt frame, and a lot of kitbashing.
The Cox body is rumored to have been the basis for the body in the HRM kit, but I can't confirm or refute this.
