The a/c compressor seized up in my I30 quite some time ago so I got a smaller belt and have it bypassed. I'm thinking about biting the bullet and having it replaced. I've been looking at the aftermarket compressor kits on rock auto. Does anyone have any experience with GPD or Four Seasons brands? Will it fit and function like OEM? Also do I need anything else other than what's in the kit?

Always liked Four Seasons, but the GPD kit (1 year warranty) shows "O" rings included, but not the Four Seasons kit (2 year warranty).
I'd say it's a toss up as they are both new units.
