Which Shifter for GTRA T3550 Trans?

I alwasy thought the back of the seat is not supposed to be bolted to the adjustable back support. The seatbelts mount to the frame thru the seat. So the belts pull and snug you and the seat into the back support. The brace is there to snug all of this tight and for rear impact. It just needs to be snug to the back of the seat. Plus some seats you will void the warranty and the FIA certification by drilling into the seat....

as far as the hood and trunk pins go:

Proper installation of a seat back brace is to have it bolted the cage AND the seat. FIA rated and current seats should NOT be drilled or have a seat back brace added, they are designed with flex intended, but most sanctioninig bodies require FIA seats that ar outdated to have a seat back brace installed.

A seat back brace that is NOT boted is a back breaker waitng to happen. if you get into an accident and the seat flexs forward and then abrubtly slams backwards, you have a larger steel bar awaiting your arrival. The brace is intended to prevent the seat from overflexing and allowing you to "fall out" from under your harnesses.

my 2 cents worth every penny
