I just got mine installed today, and WOW! It sounds awesome!
However, the tech had some fitment issues. He had the parts in thee right place (I visually checked), but the hangers weren't even close to lining up. He ground them all off, cut them to the right size, and welded them back on. I thought it would cost me a lot more than I expected, but he only charged me $50.
I kept the stockers, so if anyone wants to buy them, I'll post in the classifieds.
(As soon as I read the rules on posting there)
