They are generally part of the alternator, is that what you found with yours? Were you able to replace it separately or is it integrated into the alternator?

It is separate, the regulator is a silver box like bolted up just behind where the hood lifts up. If you are looking at the oil dipstick mine is above that (bolted to the top).
It has wires that connect to it in a triangle type shape (but only 2 wires go in).

Hope that helps

External voltage regulators were not installed after the vans moved to fuel injection- 1987 would be the last year for the external regulator.
