I just installed mine and it was a total PITA. I had the roll pin in there, but was afraid that it wouldn't hold, so replaced the roll pin with a length of music wire. THAT is not going to break, it is harder than the hinges of hell, it took a little mini pair of bolt cutters to cut it.
My question is, I have read some guys have "peened" the ends of this wire, but I don't see how, it it so hard, I could not mushroom it. How did you guys that have done this peen the end?
I ended up cutting it a bit long (~1/8" sticking out of each side) hoping that it won't "walk" out of the hole. The extra length didn't seem to affect anything, it worked fine playing with it manually.
