Different kind of vacuum gauge

[rideblue00]

I decided since i put in a new Sun retro tach in, that i wanted to find another kind of gauge to put in the other side. I did a search to find a new clock but cant seem to find one that is 3" diameter. Most are 2 1/16". So i was just surfing ebay for "vintage gauge". And found lots of stuff. Came across something called "Motor Minder" by Stewart Warner. They were going for a premium. So i just kept searching. And found this one. Made by Rite Autotronics Corp. Called "Motor Monitor". Its a little smaller, so i turned up an aluminum ring on my lathe. I made it a little big to make sure it fit the hole so no green came through from inside. I mounted it on the stock bracket inside the cluster. I made sure to test it on my other truck to make sure it works. Once i install the cluster, i will have to run some kind of line to the intake manifold vacuum fitting. The only thing that was tricky, was opening the hole on the aluminum black overlay sheet.
