USED Link Coupler Side Frames & Bottom Plate Assembly for Early ALCO Engine:  Intact and clean, this is the side frame & bottom plate assembly for the early ALCO A and B-units.  It comes with a reproduction (new) link coupler arm assembly XA11484 and original S334 screw. The side frames are firmly attached and have above average silver paint. So, please take time to review the photos carefully. I will be happy to answer questions, I just kindly ask that you inquire prior to your bid.  I do combine shipping.  Thank you!
