Parts

OK well it iced over here and i messed up my car. Anyways I need the front and rear passenger side lower control arms. And the passenger side radius arm. I have found all three of them used for less than a third of what they cost normal. Except for the front lower control arm. The lowest i have found is 60 bones. The other two i found for 25 a piece. So if you know of any good salvage sites let me know. Second question is, how hard is it to replace these myself. Any special tools required. Cause i'm looking at about 300 in labor. So i'm assuming i should have someone else do it because if it takes a mechanic that long, its going to take me 5 times that. But if someone here knows otherwise please let me know. Thanks for any info
