Thanks! That worked, but yes, now I can't get them out...I was hoping it would be simple enough to put them in, ride to the inspection, and then ride around the corner and pull them out. What did you do to get them out?
I use a piece of wire around the round part and make a handle using screwdriver.
They are normally a very tight fit. You can also try a sliding hammer like they use to pull out dents, but first try running a wire or strap around the round steel piece in the outlet and yank on that.
