I'm refurbishing the instrument cluster on my old Ford 4100 and the instrument voltage stabiliser is cactus, the same voltage stabiliser was apparently used for decades on lots of Ford products. I read somewhere that there is a solid-state replacement available that will mount in the same place- I haven't been able to find anything in online searching, wondering if anyone can point me to the appropriate part number or a source to obtain one?

From a quick look-see you appear to have a 10V stabiliser same as early Land Rover with Smiths gauges. There's an electronic one here:
Electronic instrument voltage stabiliser – 10 volt for classic cars (as BR13xx) | eBay (https://www.ebay.com.au/itm/Electronic-instrument-voltage-stabiliser-10-volt-for-classic-cars-as-BR13xx/282642726457?_trkparms=aid%3D111001%26algo%3DREC.S EED%26ao%3D1%26asc%3D20131017132637%26meid%3D12fef 6d6ff604a57a48ebfab9d24671f%26pid%3D100033%26rk%3D 2%26rkt%3D8%26mehot%3Dag%26sd%3D282642726457%26itm %3D282642726457&_trksid=p2045573.c100033.m2042)
or you can go to a Jaycar store and buy a #7810 3 pin regulator IC for around $1 and mount it to a suitable small heat sink and solder some leads to it.

They're actually a 5v stabiliser, which surprised me a bit. I gave the instruments 12v briefly whilst I was testing it and the smoke started to escape. The IC unit I saw looked externally identical to the original, just can't seem to find where I saw it online.

Thanks Rick, the Bareco one on that page will be a bimetal one same as the original (only probably lesser quality- I've been very disappointed in some of their bits), if i can't find the IC unit I'll go a genuine one I think.

There is a 5V type too, #7805, I bought a dozen once for a few cents a piece. Ebay shows one done up ready to fit:

Fitted up the eBay DC-DC 12v to 5v converter, works like a charm and even mounted to the same screw holes on the cluster casing.
