I'm sorry it took me so long to find the tech bulleten I mentioned but work has been so hectic this past week that...........
I did find it, but it was published in 1985 so it wouldn't actually apply to your car. I did check it anyway and it says to use 2.866 lbs (45.8 oz)(1.3kg) of freon so you were about right. However, I have seen quite a few cars that needed a little more, or a little less to work correctly.
Going by the pressures you were getting, I believe you may need less than normal.

Have you tried anything sense your last post?
Let us know.
