5 point harness in a car w/o roll cage...How to do it?

I spoke with the folks at Corbeau about their harness'. Acording to them, a cage is not REQUIRED for for anchoring of the shoulder belts. It IS preferrable, but they said the should belts can be mounted further back in the car and anchored to the floor, as long as the angle of approach for the belt to the seat back does not exceed a certain angle.

I can't remember what it is off hand, but I have it at the house. Their belts have 70 inches of extra belt to mount them back around the rear end tunnel, making the angle very do-able.

I am using a different solution. I have removed the rear seat, and am planning on fabricating a brace bar that will span from one side of the car to the other. The interior side body on each side will be reinforced and have mount nuts welded to the interior plate. I *think* the bar will be 1x3" 3/32 or 1/8" wall bar stock. I am going to mount it high on the body, and then angle the bar so the belt is pointed directly to the pass through holes on the seats.

I am also planning on using Corbeau's retractable harness...so the actual retractors will be mounted to the bar.

NHRA legal? Dunno, Don't care......
