Refrigerant Type: R12
I'm working on an early 90s German car that was originally R12. I believe the compressor is Denso.
So it already had 134 conversion adapters, but the high side was simply a pass-through. I'm in the process of refurbing other parts of the system, so I'm changing the ports to ports w/ their own built-in schrader valves. I went to remove the high side schrader from the R12 port and it was a bit tight, but I got it spinning (w/ resistance) and got it off.
This is what I removed.
Is this the whole schrader? Or is there a problem?

there is still a part inside. Your valve has broken.

-------------------------
Get yourself an EZ Out set at an auto parts store or whatever. I've used them to remove broken Schrader valves and so far, they never failed.
Update!
I went to Home Depot and bought a Ryobi Screw Extractor set. The smallest bit in the set, a #1, plus some Vise-Grips to hold and spin the bit CCW gripped the remnants of the schrader and I was able to pull it out.
I then realized I was still missing the end of the schrader. So I went ahead and removed the compressor, disconnected the hoses, and removed the 4 cap head bolts that hold the port housing piece to the unit. After I tore it apart, I found the small piece inside that area. Reassembled w/ some Nylog on the existing gasket, added an equivalent amount of fresh ester to what poured out.
I'm glad I was able to resolved that. Thanks for the suggestion on the extractor!

I use a tap handle whenever possible to apply even torque. I've broke off a few in the past while trying to remove broken screws
