Thanks for taking the time to post that. I went to another yard today and found that bracket in a Caprice wagon. Still no switch but I can see a problem already. I pulled the whole assembly out including the pedal.
The Caprice pedal bends to the right and makes contact with the bar on the switch. The Malibu pedal goes up and to the left on a slight angle. Do you use the bracket with the Malibu pedal and mount the switch from the other side of the bracket ? Maybe cut the top flat piece of the bracket off for more clearance ? Using the Caprice pedal doesnt look like its going to work since the throttle cable is way over to the left.
I havent taken it out of the car yet due to getting involved with a ton of yard work as soon as I got home but I hope to be messing with it tomorrow or Monday.
