RockAuto will be your friend for everything that is not sheet metal. My wife's SRX had a charging issue that turned out to be the positive battery cable. The stealer wanted over $400 just for the part. $71 on RockAuto, which you may think still sounds like a lot, until you absorb the concept of a $400 PIECE OF WIRE.

Had this happened a month ago, I could have helped you on the sheet metal--my wife was in Indiana for a week.
