Found a pair of NEW air-ride seats for M915A4 trucks in Phoenix, AZ, that a guy was selling...he originally bought them out of OK City from GL for his Deuce, but ended up selling his Deuce and kept the seats. The price was worth the all-day drive down there, only spent $150 in fuel. They were still in the plastic wrapping & bolted to the pallet they were shipped on, but both were passenger-side seats. Once I got them home I was able to disassemble one and swap the parts to the opposite side for driver's position use....the only iffy spot was on the upper cover, the top 3-point seatbelt mount required a hole to be cut over the left shoulder side, and the original hole was left open. But other than that it was pretty straight-forward to swap all the controls over for driver's side use.
I used 4 of the 6 original bolt mounting locations from the stock seat; one of the original bolt holes I removed the captive nut and installed an air line bulkhead fitting. I removed one of the 1/2-inch plugs from the secondary tank under the passenger side of the cab, and tapped in 1/4-inch nylon Parker air line. I had to drill 2 new holes in the right side of the new seat base to match the stock seats' 14-inch bolt hole centers, then welded in some 1/4-inch steel stock on the left side of the new base to match up with the other 2 stock captive nut locations. I cut the floor mat to better fit the new seat base as well as the fuel tank selector switch.
Today I fired her up and pressure-checked her; the new seat works GREAT!! What a HUGE difference it makes, much more comfortable and safe as well. I love it!
