tool changer - missing 3x9 screw and mystery pin

Hi I took apart the tool changer, belt clamp, and hot end, and in the process noted that I was always missing a screw for the tool changer locks. Also, I have an extra little pin or dowel, it fell out when I was disassembling everything in the picture. (I messed up the Dwarf board but that's another post)

What is this pin or dowel and where does it go?

I ordered a pack of Prusa 3x9 screws from partsbuilt.com, but in the meantime, is it a big deal that one is missing?

I meant to say missing SPRING, not screw.

Hi - Someone answered this question on Reddit:

"I have done the same, and found the pin goes between the metal plate that bolts and the rail slider. There is a recess that it goes into and it's sort of wedged in place. I have no idea what purpose it serves"
