A helpful hint for anyone installing Roll Bar Stays. After the hoops have been positioned, place a torch inside a section of rubber hose and push that hose up onto the point where the Rear Stay attaches to the Roll Bar Hoop. The light from the torch indicates the exact point where the holes are to be cut through the body for the Rear Stays to be attached to the chassis. You can see the set-up better in the photo above.
