I've seen some setups here that were a combination of the original pedal/arm and lokar. I never saw anything I much cared for. Too many pieces.
I got a stock, firewall mounted swinging pedal and cable from a '70s chevy truck. The cables for '70s cars and trucks are nearly all the same. They just come in different lengths for the various applications.
I picked up an assortment of cables and used a long one that I think was from an Olds or Cad. I got the carb bracket that was on the back of the Quadrajet and trimmed it down.
The cable loops around the PCV on top of the valve cover. It has worked without a hic-up on the Carter AVS for several years.
Another nice thing about it is that, it's the last thing you see when you look under the hood.
