People think changing the fittings is all you need to do. In my research the system needs to have the compressor flushed and refilled with oil compatible with 134 and the air dryer may be changed out as a precaution. The refridgerant is not compatible with the oil in the old r12 system and will cause the compressor to fail . I have seen a lot of this on the web and believe this to be a true answer.......You can easily get r12 on e-bay and it is a lot cheaper than a refit.............Most auto parts houses stock it for 35 bucks a can and the service tech can mark it up to 50-70 dollars. Trick is a license is needed to handle it but usually, on the web, an agreement to provide it to a licensed tech will satisfy seller.

A 1998 Buick would have been built with R134a.
Would have been built for R12, can be converted to R134a.
It came with R12 (Freon). Look for a sticker on the unit, as it may have been converted. If not convert it to R134a. My advice, is, take it to a professional.
Unless it has been converted over to R134 it came with R12. I suggest you convert it to R134a. R12 is very expensive.
It uses R134a.It uses R134a.

The original refrigerant installed at the factory in 1973 was R12 (Freon). If it has not been converted to R134a, I suggest you convert it now, if it is leaking and needs repair. R12 is no longer in production and the dwindling supply is very expensive. Much cheaper to convert it to R134a.
It takes R134a freon, that's it, no special type..........
