You have to have a set of gadges. Start vehicle, turn A/C to max, pressure should be in the 30-40 LB range and steady. It's advisable to vacuum system to negative pressure to check for leaks first. Don't over charge or you will burn up the compressor in no time. Also check or replace the oraface tube.

My Vintage Air unit said 1.8 pounds, both for my 71 C30 and my 66 Chevelle.
