Griffiths gave the low-down. I'll add that just about decent shop should have the equipment to evacuate any remaining R12. This is your first step. A corner shop charged me $20 and kept a vacuum on for about 20 minutes to see if it was losing any pressure.
Next is to buy the orings, new ports, new drier, oil, and freon+dye. Replace as many orings as you possibly can. You can "rent" a vacuum pump and AC manifold gauges from many auto parts stores. After replacing the parts, put the vacuum on it, then charge it up. It's really a pretty easy process. The trouble is when you discover that you've lost all of your freon a week later

Cheers for that its all a bit clearer now, I have a man in a van coming to the house to check out the 964 and also the ML as it only holds a charge for about 3 months had the dye through it 3 times and cant find anything wrong.
