Roll Bar Harness Belt Tabs

And not that your racing NHRA. but if you use their rule book and follow the guidelines you would surely meet anyone elses requirements.

I can tell you on the seatbelts, that the tabs must face in the same direction as the pulling force.

The shoulder harness if looped around the roll bar has to be captured. Not allowed to slide side to side. This can be a welded wire. The pulling force has to be level with the drivers shoulders.

No bolts or holes thru the webbing.

The real problem you run into is seat bracing requirements. If you have two drivers of different heights for the same car it is a total pain in the pa toot.
