FFG 1953-56 Ford Truck Mustang Seat Brackets

Modern seats. Classic cab. Drilled in; not bolted to hope. The bench in a 53-56 is a period piece and a two hour drive in one tells you why people change them. Mustang seats fix that in an afternoon; the trouble has always been mounting them square; centred and low enough that you can still see under the header. These brackets solve the geometry. They put a 2015-2021 Mustang seat where it belongs - centred to the steering wheel - using a mix of existing factory cab hardware and the under floor plates and washers in the box. You get power seat function and real lumbar support in a truck that never offered either. That is the upgrade you feel on hour three of a road trip; not the one you photograph. They ship in raw steel. Coat them or paint them before they go in; and plan on drilling the floor. These do not reuse the factory seat holes because the factory holes put the seat in the wrong place.

  • Modern seat; modern comfort - 2015-2021 Mustang seats bring power adjustment and support the bench never had.
  • Centred to the wheel - the brackets set seat position deliberately instead of inheriting the factory offset.
  • Load spread under the floor - included mounting plates and washers put the clamping load into the floor pan; not into four thin holes.
  • Sold as a pair - left and right in one order with the hardware that ties them down.
  • Steel construction - a seat mount is a safety structure; this one is fabricated steel you can weld or coat as you like.
  • Honest about the work - published measurement; published drilling requirement; published battery tray clearance note.
