I'd like to install a Transmission Temperature Gauge in my 1993 Convertible. I've seen the A-Pillar Single Gauge Mounts, but was wondering where others may have installed their gauge. Is the A-Pillar Mount the best way to go? Also, any recommendations on the Brand / Model Gauge to get would be appreciated. I'll be installing a Gearstar 700R4 Stage 4 Transmission with a Derale Cooler, and would like to be able to monitor my transmission temperature. Thanks!
