Power driver seat

thats the single motor style i have a few of those and a few of the 3 motor style. supposedly the 1987 style is better. either style $175 without switch $225 with switch. both switch styles are diffrent and cant be interchanged. you can however put the 1987 power seat track with switch on your 1986 seat without issue
A few dumb questions.
Do you currently have a power seat?
If it is power what is wrong with it?
Are you converting to a power seat?
If you don't you will need wiring as well.
