Leathermang - I follow your posts and agree with you. However is it not correct that you can postulate low Freon if there are bubbles in the sight glass? At least that's what I remember from the good old days. My 81 300SD looks like a river current of bubbles going through the sight glass - and all the shops around here want to put Freeze 12 in it (not going to happen).
