Going back to your original post... Did you try contacting Brasseur's Trains in Saginaw, MI?? I believe they bought the remaining service parts of K-Line when they folded their tent.
OTOH, looks like you're well on your way down another road.
I'm with GRJ...once into a K-Line, et alia, passenger car...and especially their last runs of the benchmark aluminum cars...I'd be ditching the incandescents and installing LED's throughout...like the ones GRJ makes (Hennings) for passenger cars!
I'm counting on winning a Powerball Lottery sometime soon so I can afford the $$$ side of that project...and re-equipping everything with Kadee couplers. Then there's that issue of time. The incessant, growing sound of 16 hoofbeats approaching from my 6 may overtake the aspirations, rendering the ol' proverbial 'bucket list' null-and-void in an instant.
It can happen. C'est la vie!
