You might want to check the dimensions, mostly the cockpit ones, on the Kilbourne body - they're about 1 1/2" -2" narrower than original ones and pretty much all of the other after market ones. No idea why they would do that! I make top frame kits for roadsters (Topsters) and any we've sold to owners of Kilbourne bodies have to be narrower than the rest. That diference could cause other problems too.
