'71 Power Brake Booster Check Valve (and thermal sensor)

Please, help me finding a brake booster power check valve for my Demon

My current booster check valve has been rubber coated by a previous owner, probably to plug an air leak. It works, but it's ugly.

I would like to replace it, but not sure about the one to order.

I found this valve in the Rockauto catalog, but it has three hose nozzles and mine has only two.

What the frontal nozzle utility? And if I plug it, will the valve work?

Aesthetically, I would prefer to find a twin nozzles (or maybe my old rubbercoated valve had originally three nozzles? I don't know) :rolleyes:

Need your help, thank you :)

A plug should be fine. You can start a parts wanted thread here for a used one.
