Yep i had the same problem, course i'm older than you. But i decided to go to full cage, the rules say i have to have a net, nevermind it's a S/ST car 10.90 index, i still have to have a net, not required with a roll bar for the rolll bar. I haven't installed the net yet but will have to before i comepete at NHRA. In my previous car i used 1/4" cable to mount it to the bottom bar, and a slide bar for the top. This car i used a buckle and will drill a hole in the bottom bar and mount an I-HOOK for the bottom hook up with 1/4" cable.
