Alternator Adjuster

Jaguar XJS if I'm not mistaken.

I only go for quality junk

The Suzuki Grand Vitara using the Peugeot engine had a similar threaded adjuster on the serpentine drive belt.

I'm also concerned about the use of track rod ends. Correct me if I'm wrong but the track rod ends have a swivel mount.
I would be concerned that once the belt was tightened up the alternator would twist around. A regular bottle screw would restrict this twisting motion better.

I don't think this could happen, but I'm putting an indent in each spacer to restrict the swivelling action. Had a problem with my lathe, so I'll post pictures in the next day or so. New alternator has arrived, shiny!

Some of these bushings are just to convert from 1/2" to M12, some to make an M12 screw thread a bit tighter in a reamed 12mm hole (aluminium drink can, 0.1mm). There are two bushings for the green bracket, one with an offset centre:

Adjusters and spacer washers, plus an insert of the bracket:

The first spacer in situ (this one is mild steel, not stainless):

The final arrangement:

The adjustment range is quite small, but this is compensated for by having a selection of turnbuckle centres. Once I find the right one, I'll just keep that, and the next size up. The track-rod ends are clamped by the spacers onto the ball, so are free to rotate around it. However, the swivelling is restricted by ridge on the spacers. I gave up trying to make a rounded indentation on the stainless steel spacers, my lathe was not happy; I just did two steps at about 0.75mm and 1.5mm. The final depth was adjusted on a belt sander during fitting.

Looks lovely! That odd-shaped insert is a work of art!

I wanted it to be flush with the top of the mounting holes, clear the vents below, and have the 3 holes in a straight line.
