A/C Seal Help - '92

[tjpops]

After a year in storage, I find my '92's A/C is now blowing warm though it was fine when I stored it. Regardless, my shop tells me after doing a leak test (dye/fluorescent), I have a leak at the discharge hose and the compressor shaft seal. The hose can be replaced but my shop says they can't find the seal part number to replace it. They say this is unusual as this is a process they often do (replace shaft seals). They also said a new compressor is prohibitive in cost - no kidding! Anyone able to help me determine a part for the A/C compressor shaft seal? Apparently the compressor is made by Zexal (or something like that). Appreciate any help - Thanks!
