Thanks for all the feed back. The reason I have a custom roll loop made was due to availability and the need to include a harness bar. I have the original road style bar for road use. The bar was fabricated by Scott McMinn Motorsport in record time only took a day and a half. It looks excellent Scotts welding is always superb. The main loop was made from 40mm CDC. Its difficult to insert photos into this posting - Any advise on inserting photos accepted. Neil
