since the new trucks fit on the lionel ps1 box cars and some weaver cars. as I said I like the new truck design. I would be willing to swap my old style with swivel knuckles and hidden uncoupling trucks that are on my ps1 cars to someone here who would like to have the old style for thier new trucks they dont like.
also if you are getting rid of or changing out these new couplers for the older stlye ones on your new cars. I will buy the new ones for a fare price. just email me. my email is in my profile.
