Here's my 3 MTH "Seaboard" cabeese:
The one on the right was a CA-1 cab, it has a plastic "wood" floor:
The one on the left is the cab I replaced the sides on and flipped the metal floor:
If you look real good you can see the dimple on the floor is inward not outward:
You can see the shiny washers I used between the truck and metal floor.
if you look real close at where the end of the plastic underframe is you can see the cut I made to the bent-up side lip.
The 3rd cab hasn't had the floor flipped yet:
If you look closely you can see the dimple on the outside, just past the end of the Kadee box.
Here's another photo, you can see where I cut off the claw coupler:
Also, the one with the flipped plate has a red oxide/rust Kadee box on it, you can just see the end of the metal plate where I Dremeled it off.
The one with the black Kadee box still has the metal "tab" on it (not Dremeled off yet). The shim and Kadee boxes are super glued to the metal "tab". I plan on flipping this one soon.
Hope you can see what I'm talking about!
