a/c pressure regulator broken

Hey! Does anyone know where I can find an A/C pressure regulator assembly for a '93 sc300? been looking everywhere (aftermarket parts warehouses, third party OEM suppliers, ebay, fb marketplace, etc.) and I can't seem to find one since the part is officially discontinued by Toyota. A/C went out a month ago and I'm trying to find a replacement before the summer heat comes. This link provides a picture of it and the part number even though its discontinued.

Preferably not a 92 or maybe a year or two after that since was R12 and not R134. I can’t recall exact year that change was made. Pretty sure the epv would have a different pressure setting.

I'd be curious to know if any other Toyota/Lexus models had parts that would cross reference on this one. Anyone know of any? As a side note, it's getting discouraging that replacement parts are getting harder and harder to find for the SC models.
