Stop in for a cup of coffee

did your car have the "fuel pacer" system ? I am looking for one of those as well.

it was a relay and when you gave it too much gas the driver side fender turn signal would light telling you to let off the gas in order to save gas.

I think mine has it. When I had it running it was on most of the time if not all. I thought it had to do with carb adjustment.
