My 260z is stock, but it does have an L28. As far as I can tell the A/C system is all 74 stock down to the York compressor. So far o'rielly and autozone have not been able to get the right drier for me. I had autozone order one for a 78 280z that had a different part number. Otherwise everything from 70-77 uses the same part.
Here's my question. The stock A/C drier looks good, but it was kinda open to air for about 6 months. It was all bolted up so the air(moisture) would of had to go down the high line, through the evaporator and back up to the drier. What are the chances if I just use the one that was in it that it will hurt something? It still has fresh pag on the threads and there is no sign of moisture. I might note that I'm installing an L28et in a couple months so I'll have to use the 83 compressor and I can replace the drier then for that.
