I'm going to get new o-rings for the parts I took off during reconstruction, hopefully OEM. Assuming everything lines up with my aftermarket condensor, I will hook it all back up. I know I should probably add some a/c oil, but aside from that do I need to do anything special or can I just recharge it myself using my $20 setup from Oreilly? Or will it need professional servicing after being dismembered by a Suburu?
