Hey Steve, nice to see someone building this thing. I'm the one that did the master for Jimmy, when I started out it had better definition to the moulding but when I was working on it some got sanded down a bit much.
When I built mine I cut down the wheel houses in the rear to get the rear to drop more...
Like what you're doing with yours, I have one that I'm building as a stock piece and one as a mild kustom as well.
