i finished sealing the floor around the shifter knobs, sooo much quieter. the knob near the parking brake is an adjustable high idle i installed, it can be adjusted anywhere from idle to wot, it is made from a vernier throttle out of a Cessna(being an aircraft mechanic gives me access to "worn beyond use/damaged" parts that are actually still functioning).
the truck is an SR5, it has a tilt wheel and all the gauges they put on the early, gas gauge don't work sadly.
