Have a few at TDR. Not sure if there is a difference between NA and NB. Probably a difference between R12 and R-134a but people convert all the time so no biggie I think.
Mine is going south and making noise. If you have a good one that you don't need, let me know what you want for it.
do y'all have an of the lines that go to the compressor for the na r134 at TDR?
