I've got this pair of speaker brackets. For some reason the anodization came off the one pictured on the right and got rusty. So I had it sandblasted and primered. The metal is just a hair thinner at the top and seem fine on the sides where the grills screw to. I measured a .004 of an inch difference in thickness, between the two, where the grill screws go through. I'm pretty firm on 50 bucks shipped for the pair, it's always pricier shipping from Canada.
