K-Line Heavyweights Passenger cars trucks & couplers crumbling

[toptech]

Anyone else experiencing 1990's K-line O scale Heavyweight Passenger cars with crumbling truck side frames & wheels & couplers from zinc pest impurities ? I bought 3 of them years ago & repainted them & decaled them with Ringling Bros. and Barnum & Bailey circus decals. Have been running them with my circus train, but have noticed lately a crumbling side frame on one & a broken off coupler on another. I have heard this is a problem that has happened going back years. These have 6 wheeled trucks. My question is does anyone know of or has put on trucks from another brand that works.  K-line has been gone for years and Lionel offers nothing. 2 train repair service stores I've gone to have nothing to offer as a replacement. I can't believe that other people having this problem are just trash canning them.

Could you use a Williams truck? https://estore.bachmanntrains.com/index.php?main_page=product_info&cPath=77_664_662&products_id=8836

Went to that website and it says that 6-wheel truck is sold out

That's the K-line by Lionel catalog from 2009. Those pictured don't have couplers. I need the coupler. I have crumbled ones. I went to a train store which is also a Lionel service station & they couldn't find any listings
