Thanks guys for the additional input. I'll check into those things too. Looking at the old monovalve insert again tonight, it doesn't look like it would be a piece of cake (for my limited skills anyway) to take apart and put back together with an intact diaphram. I might as well take the old one apart anyway.

At least I know I will have cold AC again here in the next few days when I get time. I have another car I can drive in the meantime.

BTW, I bought another one of these things last week. (I must be catching the disease). It's a 1987 300SDL, same color interior and exterior but with about 237K miles. It has a few issues but for what I paid (dirt cheap), it's fine if it turns out to be a parts car. But I will have to start a new post about that car when I get the time.
