I FINALLY was able to hook up the gas pedal cable today after months of bad weather, logistical delays, coronavirus, etc. The universal cable kit requires a separately-bought bracket that comes with some other parts, but the provided bracket was USELESS because it would not fit.
I even tried to cut and alter it, but the carb's moving parts would hit it so that the carb could not work properly. So I did some measuring and thinking, then went to the hardware store and bought some parts. Using these parts, I combined them with some parts from the bracket kit and made my own bracket that fits perfectly!
This is my first time converting a 67-70 gas pedal setup into a 71-72 one, and my sincere thanks to all on here who assisted me with parts, advice, and encouragement. Without you, I never would have been able to complete this.
