I was looking at this thread recently too. I have a kit that I haven't built yet and was trying to refresh my knowledge about trucks and wheels. I've long missed the boat to get BLMA 100 ton trucks and I can't find any N scale 125 ton trucks. It seems that 125 ton trucks are the appropriate truck for this car along with 38" wheels, which I can also not find. I've been trying to convince myself to try drawing and printing my own 125 ton trucks with my resin printer, and just using 36" wheels...but that hasn't happened yet. I'm curious to know what trucks and wheels people who built this kit used.
