Cannot get second rear caliper mounting bolt to align

Thanks for the great video. Regardless of what I do I cannot get the second rear caliper mounting bolt to line up (it is off just a smidge. I notice is on the new pads, the "tab" that is riveted to the piston side brake pad is on the opposite end of the pad. Also the squeal plate in addition to being riveted to the pad is bent over the top of the pad. Just thought of something, will try using both pads that do not have a tab in the same caliper.
