Replaced just about everything Ac won't work
Those gauges aren't helpin' any as they don't have R-12 temp scales, so you'll have to read pressure and convert to temp.
(In other words, read the pressure scale, and refer to the chart I posted below)
You want to read through the manual and duplicate as much as possible the test conditions they use. Depending on how much air you have over the condenser, high side press/ temp can be as much as 30* higher than ambient. I ALWAYS check what is known as COMPRESSOR SUPERHEAT which is a measure of protection of how much or how little liquid is being returned to the compressor. Get a probe type thermometer of some type, tape it at about the 8 o'clock position under the suction metal tube before it goes into the compressor, and wrap something around for insulation. Even a couple of rags are better than nothing. You want the converted pressure / temp on your gauge to be above the thermometer reading by at least 20*F If the difference is down around 10F or LESS you are getting too much back toward the compressor and in danger of "slugging" the compressor with liquid. Measure this with the pass. compartment cooled down
Once again, you need some method of GETTING AIR across the car radiator so that you can duplicate "running" conditions.
Here's a chart:
