Recharging A/C 91' Sovereign
A/C on 91' my Sovereign blows cool, but not cold enough when temps are above 80 degrees.
Does the system in the 91's use the old R-12, or new R-34?...
I don't think I can do the r-12 recharge myself w/o environmental shop machines...

Originally that car used R12 but it may have been converted? Usually there's a label on the fender with the A/C details/specs, but if not, you can tell by the type of charge ports as to whether or not it has been converted.
You'll have to google the port descriptions to see the differences.

Charging is always done via the low pressure port. Lots of information online about servicing A/C systems.
For the record, since your system may have inhaled air and moisture via the same leak through which it has lost some of its refrigerant, it would be a good idea to have it professionally evacuated to get rid of the moisture and contaminated refrigerant before recharging it with the correct amount of new refrigerant (by weight). That's really the only way to restore the system to full efficiency. They'll also vacuum test the system to be sure the leak is not significant, and they may recommend that you replace the receiver/dryer. They'll also monitor their manifold gauges to ensure the system is operating properly and the refrigerant charge is correct.
