I looked VR up for a 1990 B250 with 318 or 360 engine and both showed the flat firewall mounted solid state regulator we had on our 1970's B300 used.
In that van, there was a little VR on the back of the instrument cluster. I'd get erratic readings if it was bad, OR the ground connection was loose. Small metal-cased thing, not much bigger than the small automotive circuit breakers. If I became alarmed at rising Coolant Temp, I'd notice I also had More Gas and Higher Oil Pressure than just awhile ago. Knew it was time to work on the Cluster. I don't remember if the Ammeter was also affected.
