I purchased a couple of the original cyl. hoppers before I realized they came with scale wheels. I'm Hi-rail so... If I understand this thread correctly, I'd be happy to swap my scale wheel sets for Hi-rail wheel sets if that helps anyone out. Contact me off list via my profile info. I'm out of town for the week so can't verify what or how may I have. That's why I said I had "a couple" hopper cars.
