A/C compressor

[Royal-T-Ltd]

I need a New compressor. Where should i try to get one from. Tried the internet but didnt find any links. Tried gm parts direct numerous times and the browser crashes when I choose 1987 Buick. Anybody know the part # for an oe unit. Are there any other upgrades and/or options I can fit.

Also when installing new compressor should I replace condensor also?
TIA
