I'm wanting to know what year of body parts will fit my 1988 F-150.

I'm needing a left front fender & driver's door for sure.
I found some off a 1992 F-150 but don't know if they will work.

 

'92 fenders will not fit your '88. The front end changed in '92. However, 87-91 fenders will fit.

The door should fit though, just as long as it has the right accessories that your truck has. I'm not sure if the pwr. windows/locks wiring will work with your truck's wiring though. Might ask someone who knows more about the electrical than I do.
