Have a 94 GT and the power seat track seems to be going out. Moves up and down but there is no forward or backward movement, which sucks since i'm tall and would like to know if there is more room available out of it. Replacing it is one of the items on my to-do list, but was considering replacing with a manual track. Do manual tracks sit any lower than a power track (in its lowest position)? Any benefits to manual track aside from cheaper and less weight?
