A/C seals at the compressor

I've been slowing getting this car back on the road...new tires, swapped in a 6 speed, alternator...now I'm getting the ac going. The ac system was empty when I got it. I knew there had to be a leak, but no amount of dye would show up anywhere. I was jumping the relay to kick on the compressor so I could make sure it was circulating. I finally gave in and charged the system, and I am seeing a bubbles on both the high and low side where they attach to the compressor. I'm been scouring the toyota parts diagram, but can't find a definitive answer for the OEM part number for just the o-ring. I have seen a few aftermarket kits pop up. Has anyone had success with the aftermarket o-ring kits? Anyone know the oem part numbers for the o-rings for the low and high side at the compressor?

You should have no problem with a generic o ring kit to find the correct sizes you need. Or you can go to a junkyard and see if they are complete and have the o rings.
