Replacing Vacuum with Air gauge - Qs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm adding the GMC aux compressor (vacuum driven) and probably a reservoir tank, and I'm thinking I'd make better use out of an air pressure gauge than I would the vacuum gauge.

Does anyone know:

a) What the max pressure on the gauge is? The shocks and regulator go up to 150, so a 100psi gauge wouldn't tell me that much
b) Only on C40 and higher stock, correct?
c) Are they repro'd?

If not repro'd, where would be a good place to look? I don't see any for sale in the classifieds, or on eBay. Wouldn't think they'd be that rare!
