Dan, here's one I was working on with the '59 Chevy interior and other accessories. The tub in the Buick body is much narrower so you will have to hollow it out a bit on either side. You already have the windshield frame in place. Above are a few photos of my work to date. Mine was a really bad resin body. I also didn't like the one piece bumper / rear pan on the Buick, so I molded in the pan from the '59 Chevy. I used it's rear bumper and even the connie kit. The big challenge in using the Chevy interior will be getting the Buick dashboard in place. I don't have a picture, but I hollowed out the Chevy unit and set the Buick dash inside of it for the extra width and to mate up with the windshield frame. Hope this helps!
