Vermeer T455 Undercarriage Parts

Hey, I'm on the hunt for Vermeer T455 UC parts. At this point, I'm coming up short on the idlers, sprockets, and track adjusters. I can't for the life of me find any supplier of them. Even Vermeer is telling me it would be a 145 to 165 day wait. how is that possible. Who supplied these parts for Vermeer. I've talked to Berco, ITR, Valuepart, Intertrack, etc. and no one has an answer on this. Someone, somewhere, has to carry this stuff. Any help is greatly appreciated. Thanks!
