Pat,
I actually asked Lionel to give me the part numbers for trucks/couplers as replacements. I made it very clear that I did not want the current production couplers. I have read many catalog descriptions of the couplers and the current ones very specifically do not include the word sprung. My only point is that that description is an almost a sure bet you are getting current production couplers.
I doubt Lionel will get back to me, the tech said he needed to do some research for my specific 3 cars as 2 of them use track power for lighting and freight sounds. I did consider the idea of a donor car for the Friendship PS-1, but then decided to try one of the only 2 truck sku’s, finished goods, not parts, that Lionel sells out of the catalog. If they do not work on the box car, or even if they do, I will report back.
Mike
