I have a 1990 Mustang and I was wondering what kind of AC system comes stock on these cars, R12 or R134?

I drained the system a couple days ago because I am going to pull my motor out and I was wondering which system is in my car.

If it is R12 how much would it cost to get it completely recharged?

What about R134?


EDIT: Also, how can I tell if my car is equipped for R12 or R134? I am the second owner.
