Thank you very much for all of the feedback and advice. Here is my gameplan.

1) Replace all O-RING's and gaskets on the A/C system. (parts from mercedes benz, or a local custom rubber shop Main Rubber Supply, my grandfather has gone here for gaskets and drives a 62 diesel benz, never had any issues at all. dealership prices are nuts because they "import parts from germany".

2) Drain the compressor, replace the oil in it.

3) Replace the dryer also

4) Vacuum the entire system for an hour or more, test to see if it can hold vacuum or not and if not replace where it is leaking

5) Fill with R12, oil etc.

The only problem I have right now is finding a proper system to fill the high pressure and low pressure R12. No shops do it, I'm from Hamilton, Ontario, Canada.

What is my way around finding a machine that can properly fill this system up without coverting to 124A? Please help with this.

Here are some pics of the car, I will be recording pics and videos when I do this, thanks to peachparts







Any further advice or help is greatly appriciated !!
