Cab Seat Mount Measurements?

[AKPacker]

Does anyone have the width and length measurements between bolt holes for the cab seat mounts? My truck is currently 3600 miles away so I can't throw a tape measure on them myself. I'm looking into bolt-in seat upgrades for the long drive home when I pick it up in June.

There aren't any. You will have to custom make adapters to whatever seats you desire. Even the A1P2 Mastercraft seats aren't a bolt in. You also need a very low profile seat to start with unless you are fairly short.

I just bolted a steel plate 3/16" to the factory mounts, then bolted the new seats to that, very simple. I was going to use the 1/4" aluminum plates that came with the radio rack but switched to steel bc those AL plates had too many holes. (Those 4 factory mounts don't fit standard width car seats). On the center, I used 2 pieces of 1-1/2"x 4" 10guage box channel perpendicular to the doors.
