Replacement Trucks and Wheels

[Anonymous]

I have a half dozen Intermountain ACF Center Flow 2-bay Covered Hoppers, that I don't care for the trucks they come with. I'd like to purchace some replacement trucks, but I don't know anything about the differences between the kinds of trucks. What kind of trucks would be prototypical for these hoppers in the late 80's to modern time frame, carrying mostly cement?

Thanks,
Sheldon

Not sure what the specific problem is.

For starters, why not scroll down to 7/23,"Wheelset standards".
Trucks, 33", 36" wheels, and car tonnage are all variables.
