[Verdoro 68]

It's an addition to the throttle cable bracket. I don't think it's unique to X-bodies. The cable runs down to the transmission vs. a TH400 which has an electric switch at the pedal. I thought about tapping the '68 intake, but the boss is in a slightly different location that doesn't line up with the bracket.

Have you considered using a 1968 bracket and using an earlier A-body gas pedal-actuated kickdown? I suspect a custom bracket sounds easier, and you'd need another hole in the firewall, but maybe it would all be bolt-in?

If this bracket gets you full throttle and proper kick down, drill/tap the hole and tweak the bracket so the holes line up and you’re done.

Yeah…if that’s the intake you plan to use, slot the holes in the bracket so it moves towards the carb, then drill/tap boss for 1/4” bolt.

As said above, providing the bracket/cable/carb position arrangement gives you full throttle.
