Front end rebuild....buy new or rebuild?

Yeah. I got once I had it in my hands. Another question: I messed up the install a bit. The arrow was not 90 degrees to the control arm. My mom lives across the street from me (yes, like everybody loves Raymond) and she came over and distracted me. Anyway, can I remove the new bushing, turn it a bit and re-install it? Or are they a one use deal?
I don't know. Can you? lol You can if you're really careful. I'm not understanding "90 degrees to the control arm". Can you expound on that some?
