What after market conversion kit for AC can I user for this car? I am looking to user the current R410A in the car. any suggestions?
R132A
You can buy a complete kit or just buy the necessary items individually.
Basically you need to flush the AC system out to get rid of as much of the old, incompatible mineral oil as possible. (You don't flush the compressor, just dump out as much old oil as possible. Drier must be replaced.)
Charge level by weight is going to be different, use this formula:
(R12 Charge Specification x 0.9) – 0.25 lbs. = R134a Charge Level
Ester oil is generally used in these conversions since it can better tolerate small amounts of the old mineral oil than the PAG oil used in original R134a systems. Finally you need to install R134a adapters on the low and high side ports. (It's a legal requirement and those are much better than the old R12a screw-on connectors.)
You will lose about 20% cooling capacity compared to the old refrigerant. (Factory R134a systems use parallel-flow condensers plus condenser fans to help make up the difference.)
Thanks a bunch! where did you get this info? I saw the town car video scotty made so wanted to that same thing for the car. Thanks a bunch and will update once its done.
A friend of mine who was a very experienced AC technician (now deceased, unfortunately) taught me how to do it. You will need a vacuum pump and a manifold gauge set. The Ester oil absorbs moisture very readily so it should be put in last just before closing up the system and pulling vacuum. (Put 1/2 the system capacity in the compressor and distribute the rest in other components.) I like to use Nylog lube on O-rings and fittings since it reduces the chance of leaks. You might want to consider replacing the hoses with modern barrier hoses due to their age. Your old hoses can be rebuilt if new complete hoses are not readily available.
Just take your time and do it right. Badly done conversions are prone to the "black death" which destroys the AC system.

Does not have any AC that would fit in the car. except the trunk option which is too expensive.
