Just curious. How important are these to the rear stabilizer setup? Got the bolts torqued down to 19ft.lb, but the bracket does seem a little bent. These got mixed in with all the tools on my garage floor while replacing rear springs/shocks. Did not notice them until everything was put back together. I thought they dropped as some part of the old AHC setup which I removed, but am 95% sure they are the collar that is supposed to slip inside the stabilizer link cushion.
