Thanks,
From the BARC:
A steel roll cage complying with the MSA Blue Book shall be installed. A rigid roof of sheet metal (minimum l.5mmsteel or 3mm aluminium) shall be fitted to the roll cage. The roof must cover the whole perimeter defined by thefour main tubes at roof level. It may be fitted either by being carefully welded to the main tubes, or by beingbolted to substantial brackets welded to the main roll cage tubes. The roll cage shall be fitted with door bars toboth sides of the car at hip level. Cross bars of the same material / cross section as the roll cage or solidrectangular bar of at least 5mm x 50mm shall be fitted across the car between the front feet and the rear feet ofthe cage.
If anyone has a copy of the info in the Blue Book, or even just a couple good pictures inside the car, that would really be peachy.
