Answer -
What do you mean by MATERIAL.

In order to recharge your A/C system you need special equipment such as GAGES and a VACUUM PUMP and the knowledge of knowing how MUCH OIL and FREON to install.

Answer
You will either have to use the original R-12 freon or a compatable substitute. OR you will have to convert the system over to the R-134 newer type of freon.

Either way you will still need a set of A/C gages.

A Vacuum pump.

The knowledge of HOW MUCH refrigerant oil and freon to add to the system.
