Hi Curious,
First and foremost I greatly appreciate you finding that part cheaper and explaining this. I have an 05 LS and my lights have been pointing dangerously down and I am just about sick of that annoying AFS light blinking. Also thanks for the explanation of the installation.
By no means am I a mechanic but I can handle some things. I crawled under my car and sure enough on the rear axle, drivers side I saw exactly what it was. My bracket was broken probably from like you said, something has to break. My question is does that part you found come with this new bracket or am I going to have to make one? Thanks a lot for your time!!!!
