you could try ac racing i have propegs that mount on the frame and the front bolts like it does standard but i cant see why you could'nt just hack off the front and slide it over the front mounts. but your best bet is to call ac and get measurements first.What nerf bars do you buy for an aftermarket chassis? I have a Walsh fram and it has the nerf bar mounts on the front and rear, and i dont know what to buy.
