Lonnie, this may not be what your looking for but this is what I did. I simply could not get the pivot rivets to set and I did try it with the rivet tool. I simply could not do it. Bad rivets or tool or what ever. Some say its easy. I found it extremly hard with what I got.
So, I took one of the rivets to a machine shop and had him to cut me 10 pieces just like the rivet with some threads on the bottom.($20) I then stopped at Ace Hardware and got a couple of the small acorn type nuts with the teflon in them for self-locking.
I loved it!!
I would send you a set but I gave the last set away to a bolter about a week ago.
Just a thought pal.
These are NOT good pics but you can get the idea.
The first batch are a little long and had to be cut off a tat but the next batch, if there is one, will be shorter.
