P&D interiors are not compatible with vertical can motors. They can only be used in Lionel dummy units, trimming to fit. I've used the P&D interiors in F units and E units and I would think that they could easily be modified for Alco cab units. But again, only in dummy A units.
I have also had some luck with adding detail to Lionel interiors. I mostly model Santa Fe diesels, although I have some other roads. In studying Santa Fe interiors (F, E, PA, but not hood units like Geeps, etc) I learned that Santa Fe painted their interiors gray. Lionel has used red on F's and PA's and silver on the E6 they once did. I looked at the Atlas F's I have and Atlas painted their interiors black. I then started looking at prototype photos and for the most part you can't tell the color of the interior and they usually look black. I mention this because one of the annoying things about the china drives is that the can motor is located in the diesel cab and the interiors all have plastic hiding the motor. It is not as evident in Atlas engines because they used black for the interior. If you try to detail a Lionel interior, you can paint some of the parts of the cab, like the speed recorder, control stand, etc and it will stand out a bit with a black interior.
A couple of other things I did were to add sun visors (they come in the P&D kits, but are easily modeled) and removed the Lionel cab lighting and installed mini LED's on the roof where they were located on the prototype, which is roughly between the engineers head and the cab window. (You would have to verify that because I posting this from memory.)
I'm surprised Lionel doesn't have interiors available any more. I love the P&D interiors but if you have a lot of engines to do, it gets costly. For me, having a few for show is probably good enough. The drives on later Standard O diesels are easily moved between units. For the F units that have P&D interiors, I moved the motors to the B units.
The computer on which I had pictures stored on is down. I hope to salvage the hard drive, but I don't have anything to show.
