Got it. I was able to change it without taking anything else off. Everywhere I saw said you either had to take the bbl off, or take the gas tube out and turn the delta ring so you could slide the rod out there. It took a little persuading, but I was able to get it back far enough to get the one on off and put this one on.
The way I got the c-clamp back on was pretty simple. I held it in place with some tweezers, and pushed it on with the blade of a knife.
What do you think?
