We just realized we need a kickdown switch for our 68. Keep in mind, we bought a shell without motor or transmission and we're missing lot's of parts and we've never built a car before. We put a 1976 400 w/TH400 in it. We are starting to wire the car and realize the kickdown switch should mount to the carb. Our's is a holly 650 attached to a an edelbrock performer intake. Also, we are using a 67 throttle assembly which uses a rod vs. the cable. Our question is, what kind of switch/setup can we use to make a functional kickdown? We understand the original kickdown is quite expensive and since our car is not a 1000 point restoration, could we set up a different more economical way? We've seen a few options that mount to the gas pedal, but we do not want to go that route. We want soemthing on the carb... any ideas? Anyone done this before? Thank you
