An additional adjustment is possible on the 1964 Tempest sedan and coupe front seat to satisfy the requirements of shorter people. The adjustment is in the seat track itself, rather than in the floor attachment.
First move the outer seat belt anchors, pulling the floor mat away, and unbolting the seat adjuster from the floor. Lay the seat back to expose its underside and the seat adjusters. Now remove the Phillips-head screw frm the rear part of the upper seat adjuster. This screw acts as a stop to limit the forward movement of the seat.
Then slide the lower track to the rear, and tap agains the leg to reposition the rollers so that the latch can be moved the two additional notches availabe. Reinstall the screw, make sure the adjuster wire is hooked up, and reinstall the seat.
The complete seat, or the rear only, can be raised by installing 1/4 In. shims between the floor and track. On two-door models, the seat back can be shimmed with 1/8 in. spacers under the stops.
After underside of seat is exposed, screw is removed to adjust seat farther forward.
