Hope someone can help me out! How can I recharge my air conditioning in my 1968 300? Am hoping to be able to do it myself. Thanks

 

It probably was designed and built with refrigerant 12 as its operating fluid. You can't get that any more but you can probably find a conversion kit to change it over to R 134a. Search the web. Parts for the system are going to be hard to find.

 

Thank you!
