I'd bet what you have is M12x1.25. Someone could have replaced the knuckles at some point?

I appreciate the input but they are 11mm. I can also tell that the thread pitch is slightly different on each end of the studs but both ends will screw all the way into my 7/16-20 thread sizer. That would be the thread sizer that doesn't have an 11mm option. I don't even have any 11mm taps. Getting a set on order though.

Finally found some brake fittings that are very close to OEM. Had a couple of near misses before I found these. Slightly shorter unthreaded lead-in but otherwise dimensionally more or less the same. Not sure about the silver vs yellow plating. Some of my OEM lines appear to have been yellow but some, like the rear brake cylinder jumper below, were clearly silver.

One of the previous near misses were these from the company that @J Mack referenced. These are the same fittings that they are using on their premade Toyota brake lines (they sell premade lines as well as fittings and line). They are also more or less perfect except the nut is an 11mm wrench. Did not know that until I started comparing them to the originals.

Nice find!
It has been tough to get a minute to sit down and read in here for more than a few minutes!
