I went and looked at the tag that expired on the car. It has no et time? Just says: NHRA Sportsman Certification? Do you know what exactly specs out as?

We just had an S & W chassis certified to 6.00. The only thing (besides the helmet bars) that I can't tell from the pics. is on our chassis, on the upper frame rails, where the 6 pt. cage is attached, it is double wall tubing all the way to the bend at the seat back. Where the upper rails are reduced down, they just slid them all the way to the bend and then plug welded them showing the double thickness. Also where the two upper rails meet behind your shoulders is double thickness too. Hope this helps.
