Message	I looked around, no sticker under the hood covering the original A/C sticker. Nor was there any sticker elsewhere that I could find. I was picking up some cans of R134 for some other cars at PepBoys and when I mentioned my Z the guy was positive it had already been converted at some point considering it's been outlawed since 1993 or so. He didn't seem to think the lack of conversion sticker mattered. Regardless, my AC is weak in the Z on these 90+ degrees and I was hoping to find some cans of R12 on craigslist/ebay to top it off. If it's already been converted to R134 then obviously I'd just add R134. But the question still remains, how do I tell? The hi and lo side fittings look stock with no adapters installed. My car is a 1990 TT fyi. Thanks
