I would use the Holley bracket. It will be engineered to work with the carb.
Looks like they recommend this kickdown bracket......

This bracket might work for the throttle cable. It is carb mounted. It might require a longer throttle cable like a Lokar since the stock throttle cable might not be long enough to reach a bracket mounted to the carb. This bracket is for 4150/4160 carbs.
