Re: AC question
I'm pretty sure 134a.
Check the door tag on the driver's door for the month and year of production. Then call your friendly local ford service dept and tell them the make, modem, and the year/month of production. They can tell you what it came with.
If it is R12, the retro fit kits are about $30 with 2 cans of freon, the adaptors, and the hose to fill it.
