I have several 1970"s 8' mirrored sliding closet doors - very heavy. The existing hardware is old and the doors do not slide properly. The existing track looks fine.
The numbers on both upper and lower hardware is ACME 3750337
Thanks

Your parts look like they match our 23-026 bottom sliding door guide and 23-027 top sliding closet door roller. Please look them over and let me know what you think.
