Air Conditioning Question

[1977granada]

Hi everybody. It's been awhile since I have been on here. I had a question about the AC system in my 77 Granada, Inline 6. i had the POA valve on the fire wall apart when I did the heater core and I am just now getting it all back together. Is there an available o ring kit for the ac sytem, or should I just go to the local hardware store and use regular o rings? I know that it needs to be pulled for vacumn and checked for other leaks in the system, but I at least want to get this part back together. The car was off the road for several years and I guess from sitting the freon that was in it leaked out.

Thanks for the help
Mike

Ford had available o-rings back in 1998 when I did mine. I imagine they are a pretty standard size. I don't have a part number for you.
