It's been awhile since I messed with this B unit, but I did some more work on it, and then body mounted Kadee's & the pilot to it's leader. The diaphragm is from Keil-Line and it allows close coupling and runs on my 072 curves.
I also swapped out the rear steps on the A unit to get rid of those stupid shorties. Looks much better with full length steps I think!
The B unit just needs painted but it's almost 100 degrees in the garage.
