Hi Ken, and thanks for your input'. I installed the trucks from OK on the car but, because they are soft lead, they bend. The wheels are nice stainless steel, but the trucks cannot be lined up correctly. I also installed Kadee 720 metal couplers. They're Supposed to be O gauge/O scale, however, more O scale. No good as I want to pull this car in my O gauge consist.
I found the CZ trucks on [Model Train STuff] and ordered 2 sets. The reason I'm not crazy about the O scale couplers, (I have converted several cars) is the don't hold up as well and often disconnect on curves. Don't get me wrong, I like the prototypical looks of changing trucks and couplers to O scale. But, I prefer the reliability of the O Gauge couplers, as they rarely disconnect. and when we're talking about cars built from kits, with extensive details bringing their worth up to a few Hundred Dollars... well you get the picture........
Ken when you added your trucks to the OK car, did you have to add a bolster, or did the fit right without adding one???
