1964 c10 292 throttle linkage

[Mike_The_Grad]

Hey everyone I already posted on the parts forum but I'm looking for the bracket at the firewall that connects the throttle pedal to the throttle rod. My dads 1964 c10 originally came with 235 inline 6, but we swapped in a 292. The 292 being a taller engine, the throttle rod bracket is too low and it's the intake manifold. Also the throttle return spring is bent over the intake manifold and after so many hot and cold cycles the spring gets weak. This results in a high idle at stops that can't be brought down by trying to stab the throttle. The truck has a 4 on the floor. Thanks
