Thanks Lou and Dan. I have done a search with those numbers and it looks like the DS is out of stock and no longer available. Time to find a good spare everyone.
Next question, my door latch locked up and wouldn't work on me yesterday. I finally got it open and decided to remove it and clean/fix it. I found the following plastic piece inside the mechanism. Does anybody know if it belongs there or is it something that got stuck in there by accident?
I am going to repost this in another thread in hope of a quick answer so I can get the door back together. My apology for a little spam.
It does look like a plug of some kind. It didn't really stop the latch from operating but removing it seemed to make for a more solid latch closure. It was resting above the top strike plate.
I just finished reinstalling the latch. That is not a job I want to do very often. Getting it out was easy but reattaching the actuating rods and the locking clips that keep them in place was a nightmare.
