started to work in AC that hasn’t worked for a while. Rear AC never worked in the 7 years I’ve owned it. So replaced rear expansion valve and oriface tube up front. Replaced O rings where I could since I didn’t know where all the leaks were and the system was empty. Vacuumed for 45 minutes and let it sit for about 10 to make sure it held pressure. Started to refill system and by the time I was almost done with one can low side psi was over 100, high side would get to 75. Compressor was just starting to cycle, short. I stopped at that point because of the low side pressure. Compressor is not noisy. Not sure where to go from here. TIA

I'd keep filling to see if pressure would normalize as the compressor was able to cycle.

If the low side pressure is high then the compressor has had it. But it's strange for the high side to be lower PSI than the low side.
1/2 can is normally about 8oz, my 96 takes 3lbs and it's a 2 door so no rear AC which would mean less refrigerant. Are you sure you're seeing 100 PSI on the low side? Compressor wouldn't be cycling at that pressure. Low side pressure switch cuts out no higher than 20 PSI
