Jaz aluminum seat mounting

Oh. I just noticed something. I’d have to look back up the NHRA rule, but my memory says that the back of the seat has to be within 3” of the crossbar. Do those extensions qualify it as such ?

Maybe the 3”to bar came from distance back of head/helmet needs to be.

Ps. Not busting chops. Lol. Just curious. I’m catching up with and/or learning all new rules now. Lol.
I'm pretty sure they don't want your head too far forward away from that Loop and they don't want it above, obviously LOL. Definitely bar a needs to be attached to the back of the seat. No matter how far or how far backward it is they like it attached to the roll bar.
