I'm finally done.
These trucks are so fiddily I will not do the other A unit. They turned out great, but not as big a deal as just lowering and fixing the pilots mounting steps and other scale items.
But, here are the results.
As you can see here the side frames narrowed to scale leaves plenty of room for electrical conduit, sand lines, etc. to be added under the frame.
I hope ya'll enjoyed this little project.
