The low side pressure will be about the same as R12, the high side will be a bit higher.
The expansion will regulate the pressure based on evap temperature. Thus it will reduce or increase low side pressure as needed.

I'm resurrecting the AC on a 1990 560SEC and the owner wants to convert to R-134 (I know, I know...) We've got everything installed, replaced, flushed, and ready to charge, except for one small bit of info: What pressure should I be seeing on the low side when the system is fully charged? I'd rather use my real gauges to check this and not just rely on the cheap gauge with plastic fittings reading in the green area. This is my first time charging a 134 ssytem.
