Need help finding correct thr. cable bracket!!

[80Camaro]

Anyone know of a good throttle and trans cable bracket for my setup... RPM Air Gap, Holley Avenger, "71 thr. cable, and TH350 cable. I've tried a couple that the cable mounts weren't far enough back away from the carb. (too much slack). The one I've had on there for a little while is the little blue aluminum one from Jegs... but it's too flimsy and bends. The one that's supposed to be for a Vortec manifold does not fit well either.

What are you using??
