There are four specific brackets: right & left inner and right & left outer. These bolt to the floor pan, then to the seat tracks...raise and level the seats.

Bucket seats were part of the 1965/66 F100/250 2WD, 1966 F100 4WD Ranger package, but there was no such package after 1966. Bucket seats were optional for all 1967/72 F100/350's, Rangers or not.
