I'm looking for comfortable front seats for a 1981 Trans Am that will bolt right in. Doesn't matter if they are power seats or not. Anyone have any suggestions? Also, the cars temperature runs around 190 degrees and I want to put a 160 degree thermostat in to keep it cooler. At 190 it pings really bad under hard acceleration. I use the best gas I can get and octane boost. Anyone ever went from a 190 to a 160 and if so, what was your experience?
