JConcepts unfortunately has no plan to any time soon. Already checked. I put the word in their ear though.

As for getting by with the stock body...

Use Gorilla Tape, Drywall Tape, Shoe goo, etc.

I focused heavily on reinforcing the hood and roof area as well as body mount locations. I have only one weekend on the body, (Friday practice all day, Saturday Qualifying, Sunday Mains) and it took a few hard wrecks. The body is holding up okay so far. I actually placed about a millimeter of foam on the front shock tower to cushion it a bit, rather than having straight aluminum hit the body.
