When I did my rollbar, the main hoop holes were easy, it was the oblong hole for the rear brace that was the challenge. I went through all my wifes Christmas wrapping paper until I found a roll that had a cardboard inner core tube of the same approximate size as the diameter of the rear brace tubing. I cut that perfectly to fit to the top of the body where it would pass through. I then covered the area of the rear deck of the body where it would pass through with masking tape, and using a Sharpie pen, I traced the outline of the cardboard tube oblong shape exactly where it would pass through the body. It worked out great, and was easy, cheap and foolproof. PM me if my rambling post has confused you!
