I'm curious about other models too. Sadly salvage yards don't work like they should here, there's no rummaging around a yard for the parts you need. I do have a 98 hilux which I'll check.
Re the speedo needle, I refitted mine while driving on cruise at thirty (fifty). I don't recommend this...
The trip counter in my 80 has finally given up after about 600. A plastic lever that connects to the reset push switch has sheared off, and while I've glued it back together, suspect it won't last.
I don't expect this is the most common failure mode for a speedo, but this assembly doesn't seem...
