That angle bracket may actually be original or part of the monarch dial indicator attachment "package"... I picked up a cool original one from guythatbrews and on a hunch I put it on and the angle bit is an exact match for the rod on the indicator. Either that or it is just an elegant home made version.
Good to know that is original though. I'll keep it on when I take the saddle off to clear the mess under it. I guess Monarch was really serious about keeping any mechanism flex to a minimum!
The "kick-out knob" (for lack of a better way to describe it) is what actually moves the lever when the pinch bolt hits it. You can see it here on the front of the saddle:

If they work the way I expect them to the rear one is missing and if you used the pinch bolt the saddle - or the handle more specifically - would just ram into it without doing anything. Given that extension is original I'm betting one would clear it if I took the bracket bit off the front.
Thanks for the heads up on the bracket being one tooth out. I'll have to pull that front panel when the time comes and I take the various rods off. This weekend I noticed that some of the rods are not flush with the end bearing support block as well, so I'm guessing someone messed with them and didn't get them back timed properly. Also the bushing on the saddle handle is very worn so I'm going to have to re-make them as well. There is a lot of slop in the handle on the rod... I'll have to beg/borrow/buy a 3/4" square broach to get that done though. lol
Thank you for the feedback!
