Landing Gear crossbar pin replacement

[ADP1723]

Hi everyone, I'm trying to identify the replacement pin/part that I need to fix the landing gear on my 2007 Mountaineer Edition 342pht. I've done a lot of searching on here but I can't tell if those threads are talking about the same part, so I apologize in advance if this has been covered somewhere!

Basically I'm trying to find a replacement for the pin that goes into the landing gear extension bar on the opposite end of the motor, which you can remove to adjust the "drivers side" leveler independently of the "passenger side" leveler. There was a weird S-shaped pin in there before that I think the previous owner used as temporary fix, but this broke into multiple pieces. So is this pin a "shear pin" that I've seen mentioned on here, or is it something else?

And can anyone point me in the right direction on finding a replacement?

Thanks so much!!!
