I have a 1978 Ford Thunderbird with a faulty driver's power seat switch. I have had it fixed four or five times. The seat, when fixed with work for maybe a few days or perhaps a week and then quit. The Switch and plate can be removed cleaned and reinstalled and it will work again for a couple of days, maybe a week and then stop working again. Does anyone know of a manual driver's seat seat tract that I could install so that the driver's seat could be adjusted forward and backward.
