Pin missing from 550 motorcycle mount

[Galanity]

Hi everyone, first time poster. I looked through existing posts but didn't see a match.

I have a 550 and motorcycle mount. The left pin (see photo) has fallen out, leaving only the right pin for security. The Garmin webpage says the 550 mount is discontinued, so I can't get a new one.

Does anyone know what type of screw I will need, to fill the hole? Any help would be greatly appreciated.

Here's the mount, with the arrow pointing to the missing pin.

Update: I contacted Garmin customer support, and they told me they didn't know what type of pin to use. They offered a 20% discount on a new XT, so I went that way instead.

Garmin did say that my old 550 would be permanently deactivated sometime in the next few weeks, as its serial number was used to get the discount. We'll see.

So now I'm learning what the XT can do.

Hi Galanity, I did look through my GPS "stuff" in my garage. I had a couple of 550's years ago and thought I may still have a M/C mount but unfortunately there was no mount, sorry. Hope you like your XT.
