Hi Joe, I got the kit from Jeg's actually. It is designed for NHRA, and best I can tell from the rule book, a cage built to NHRA will pass for SCTA. But, yes, I am also checking and measuring again before each weld :)

Thanks Mike! How's the other side of the world this time of year?
It's not hockey season, that's for sure. It's hot and we had our first thunderstorm last night. :-D
Your project is coming along nicely. When you fit the cage tie it into the cab where ever you can. (Ron Fournier, Metal Fabricator's Handbook).

Hey Glen,
Will do on the vacuum line, was planning to do that near the turbos anyhow.  :-) Roll cage is mainly 1 5/8" .134 wall. With the NHRA rules, the cage cannot be below 0.118 in any place and 0.120 wall usually doesn't make the thickness requirement in the bends, once typical manufacturing tolerance is included. So 0.134 is the best we can do. The less critical parts are from 1 1/4" 0.134 wall. Are there contact names/emails for the truck committee on the website somewhere?


Mike, good to hear you've heard of hockey haha jk  :cheers: should be only of the start of rainy season there I imagine...  :|
Good point on the tying into the body, especially since the body on these trucks are essentially 2 shells glued together  :-o

I've used some of the Jegs kit myself, but replaced the 1 1/4 pieces with 1 5/8 though out. You can get replacement 1 5/8 from Jegs pretty cheap. Phil

What Phil said. ALL CAGE TUBES must conform to the minimum requirements in the Rule Book....The only exceptions I am thinking would be for the seat back reinforcements, as discussed on some other Builds here. I`m not the Tech Chief though, so run all your stuff through the Committee Chair for your Class.... :wink:
