Can I install a middle 3rd seatbelt on my1968 F100?
Working on making my 1968 F100 roadworthy again and safe to drive my
family. I'd like to install 3 point harness belts with a third belt in the middle. It
has two lap belts. Was a third belt an option then? Is it possible/reasonable to
add a third 3 point belt? Or even just a 3rd lap belt?
