I have to replace both REAR Upper control arms on my 08 trailblazer. They both rotted right through and most of them are missing. I ordered (2) new arms, but I see there is an orientation to them, with the bushings welded on angles to the strut piece of metal. Can someone show me the correct direction and orientation with a picture of how they should go? Does it matter which end goes up front or which end goes to the rear support attachment? Thanks for any help!
