Hello all. Just bought a 70 AMX , 390, 4 spd, GoPak car. Been after one for a long time and excited to have it. I have owned many muscle cars and typically put AutoMeter gauges in the car in an under dash location to give me back up info and take away worry about old/failed stock gauges or sending units. This was easy in my Stage 1 Buick, Camaro and Mustang, but not sure if sending units are readily available for the 390. Has anyone installed either electric or mechanical aftermarket gauges and can you share what you ended up with for vendors? Thanks
