I found that I really needed to enlarge the FFR holes in the body to keep from putting stress on the WS. I had to cut about 1-1/2" off the bottom of the passenger side. Once you have it sliding in easily then evenly line up the WS to the lip of the body using a tape. Also if you have a bevel gauge you can make sure both sides are set at the same angle. Then mark your posts with a sharpie and drill away after removing the posts from the frame.
