Atlas O 3 rail trucks and / or couplers extended long shank style 3 rail

Do you mean the long ones that are used under the 89' flat cars? I may have some of those.

The coupler and shanks on the cushioned boxcars like the 50' PS-1' are roughly 2-3/4" from where they mount to the frame and the coupler face. He may be looking for those. However, if you have 3-rail trucks for 89' flat cars I would be interested in 2 pairs if you have them assuming the original poster isn't looking for them.

These would be the ones used on the 60' Berwick boxcars. They may be the same as the 89 foot flat cars but I do not own any of those cars to compare them to. They measure 2 3/4 from the coupler end to the center screw hole that mounts the whole truck assembly to the car. Atlas website does not show these couplers and the separate sale trucks have the shorty couplers only. If anyone has any please email me through my profile. Thank you for any help with these!   Paul

Well I thought I had the flat car trucks/couplers but can't find them now. Musta got rid of them already. My apologies.

Sorry but no the 60' Berwick long shank 3 rail couplers are still shorter than the 89' 3 rail long shank couplers. I know ecause I originally converted some of the early MTH autoracks with those berwick shank couplers and they are not quite right.

Paul-

I have a pair of 3-rail trucks with rotating bearing caps off of an Atlas 60' auto parts boxcar, plus another set of Atlas trucks with rotating bearing caps that can be used with Atlas' #6942 adjust-a-coupler kit. Asking $25 for the trucks with couplers and $15 for the trucks without couplers.
