I have a 87 that is factory stock, thinking about lifting it 2 1/2 inches or so. It's a manual and I don't mind the taller gearing from taller tires. Maybe a 255/8515 ?I'm into tall and skinny but the selection is slim in a 15 inch rim.
The truck is up in Maine so doing it myself away from my home/shop would be a pain. Parking lot job maybe
