AC Manifold Gauge Fitting?

[demarpaint]

Mods please move if needed.

I have an 88 Ford E-150 with an AC that needs to be topped up. I have R-12 in the system, and R-12 to add to it along with a set of R-12 manifold gauges I inherited from my FIL. I need an adapter to hook up the high side to get a reading from the high side. IIRC Ford used a smaller schrader valve for the high side than the standard size a typical R-12 manifold high side hose fits. Is anyone familiar with these older systems and can link me to the fitting I need? TIA

Since R-12 is the old banned refrigerant (since 1996) accessories for it could be a bit hard to find. Maybe something from this company?

^ Thanks^ This looks like it might do the trick? But I'm not sure. https://www.toolsource.com/adapters...-straight-adapter-14-in-x-316-in-p-64377.html

I was hoping there'd be another old Ford owner still using R-12. LOL

That will work I have an old one that has a short hose I also believe they made them as a quick connect.

Great! Thanks! I thought so. I'll check NAPA first, if they don't have it I'll order it on Ebay.
