I looked forever to find an aftermarket or alternative door latch for my 580k Case backhoe. These things always seam to wear out and the dealer wants an arm and a leg for them. Well, I finally found this guy. I ordered the latch, and it was a perfect match. I just thought I'd pass the info along as I see several of you have case backhoes.
