I think you are confusing condensor with the evaporator.
I have no experience with vacuum pump made of fridge compressor.
However, you can get a good quality dual stage 3 CFM vacuum pump for around 15k.

As you have already dismantled the AC system it is advised that you also remove the evaporator unit and clean it as well.
Buy new O-Rings and the recommended oil as per the requirement of the compressor.
When filling refrigerant from the can never invert it, if the can temp goes too much low put it inside a bowl filled with hot water, you can also use a hot air gun but be gentle with that.
If you can afford, buy a 30lbs cylinder and fill it by weight that way you will never go wrong, but you will need a weighing scale for that.

Once i was at shop selling these cans he showed me both fake and genuine Klea cans. I don't exactly remember the quantity inside the cans but letterings used on the genuine was clear and bold and those on the fake were dim, like if someone had taken photos of the genuine can all round and then reproduced those images on the counterfiet can.

no confusing shabbir bhai condensder is located front of car radiator and evaporator is under the dashbaord of car. I hv only pull out evaporator for fins cleaning because it is difficult to wash inside the car throughly.
