Got a surprise in the mail today – one of Prototype N Scale's custom run Atlas Pennsy PS-1 boxcars. Looks good with the 8-foot door. I disassembled it, grabbed one of my painted test-shot X58 floors and proceeded to the milling machine. I milled off the cast-in coupler box on the Atlas floor, and milled away the floor areas around the extended X58 draft gear boxes. I then drilled new holes in the Atlas floor and attached the X58 coupler boxes with #00-90 screws and nuts. I also swapped out the Barber S-2 trucks for ASF A-3 trucks.
Still have to lower the end tack boards, but that would take more time that I had today.
