I tested if all (warning)lights worked, and everything looks fine. Another job that can be crossed off the list.

And today I uninstalled the gauge cluster once more.
I drove the car today. No more ticking noise from the speedometer, no more jumpy speedometer needles, just a nice, smooth speedometer. I found everything works fine except for the trip meter.

The trip meter worked fine on the test bench last week. Somehow it doesn't roll over, while the odometer works fine. If that were the only issue, I would simply have ignored that, as I hardly ever use the trip meter on the AE86. However, I also experienced a secondary issue: the speedometer was about 7 kilometres off as well. That's also something I could live with, but since there are two issues at the same time, it's better to fix them immediately.

So, I'll disassemble the cluster once more and see what's causing the issue with the odometer and if that can be fixed. I'll also investigate why the speedometer is 7 kilometres off, as I put the needle right on the 0 mark when it's not driven. I'll probably use the speedchime signal to measure exactly when it's at 103km/h and then adjust the needle to the correct position.

Still no horn button, so the good old Toyota steering wheel was put back in its place.

That's indeed a very fine looking steering wheel, matches really well!

What's the trick to fix a jumpy tachometer? At low engine speeds mine sometimes starts jumping.

The trim piece looks fixable, should be possible to put some structural reinforcement on the rear and glue it together, then plastic weld the front and try to imitate the texture. Alternatively, all plastics can be covered in fake leather or real leather.

Thank you for the suggestions.
I tried glueing the back, but as the part is stressed when mounting/unmounting, it's nearly impossible to only fixate one side and not have the other side break. I'm a bit hesitant about plastic welding it myself. I tried to do this on one of the side repeaters, but I had another spare, and those are relatively easy to find.

This part really seems to be a problem to find. I think this is probably due to the owners stripping the panels on the A-, B- and C-pillars, but not the roofliner.

About the jumpy tachometer: it's often a bad ground that causes that. You could try to clean all the connectors of the gauge cluster and see if that helps.
