I ended up making my own. It turned out to be a good little project but very easy for someone that is comfortable with soldering electronics. It was a cheaper than the new ones. You can buy most of the parts at Radio Shack. I can provide more details if you are interested.

I found this a few years ago, appears to be the same part, but no specs. Good chance it would work.

If one of you guys wants to make a few of those regulators, they would probably be bought by people here.

Here is the URL link that got me started: http://www.datsun2000.com/tech/dash_regulator/" onclick="window.open(this.href);return false;

I closely followed the instructions on this page: http://www.alpharubicon.com/elect/build ... nytoyz.htm" onclick="window.open(this.href);return false;

I purchased the regulator and capacitors from Mouser but later determined that I could have bought all of them at Radio Shack. The only thing that they didn't carry was a case that I felt was appropriate. I will attach some pictures.

Here are some pictures from my regulator project. It is not too pretty but it works.

Could you fit all that into an old VR case? Then it would look stock.

I think that it could fit into the old VR case with a little creative electrical design. The challenge was grounding it through the VR case and then ensuring that everything remained in place with the normal operating conditions of a car. I think they would recommend "potting" it. I think that is the right term. Basically it means filling the case with an epoxy-like material that does not conduct electricity. The potting material is not cheap for small quantities. Just my research and thoughts.

Certain types of Silicone would do the same They are non conductive when dried , be sure to use correct types as regular silicone will "eat " copper and brass when wet and cause and open circuit

A 510 regulator works if you can find one

I tried one of the 510 ones. I got very erratic readings. I have it in my spare parts kit for road emergencies.

The other consideration that I forgot to mention is that the potting matereial needs to be able to withstand high temperatures. The little modulator heats up a good bit. I have forgotten the normal operating temp range.
