A new owner of a G11 PMC-Eight here. I've been focused on getting a pier installed and the pier plates aligned. But, tonight I noticed that the antenna for the wifi didn't look quite right.
Further inspection revealed that the pins that allowed the antenna to pivot were indeed broken.
I was able to remove the remnants of the plastic pins using a pick. I went through my stash and found that tiny screws, that are in eyeglass repair kits, fit perfectly. I was able to screw a couple of them in the existing holes without issue.
