R12 service port fittings

[forestg]

I have a Sanden 508 with charge port tappings on the head. Where can I buy the R12 schrader service fittings to screw into these tapped openings?

1st confirm the thread. I believe they are 3/8"x 24 O ring. If so the MEI/ Air Source number is 8900 for 1/4 flare port. 4165 for low side 134a port and 4166 for high side 134a port.
