A full 8.50 cage can be made using 1 5/8 tubing. Either .120 DOM, or .093 CM.

Talked with the nearest NHRA inspector to day.  He was very helpful. The roll bar should be behind and above the tallest driver's head.

I'm to send him pictures as work on it.  He suggested I tack weld the cage together and then he'll look at it.

That's the best plan and will insure that it passes when it's finished and you get your cert.

Don't try to skimp on any of the wall thicknesses, they use a sonic tester to verify the tube thickness.
