If you order polished calipers from SSBC, the pads will be unique to their setup and not a match to the factory pad. I found that out on my kit that I bought from them for my 69 Dart. They offer different color options of powdercoating for their calipers and so I figured that going with the polished aluminum would be the same as the rest but they were different. I found out by calling the tech lline about some parts that were in my kit that didn't fit anything that I had. That's when I was informed of the different caliper used in my application.
Just a heads up!
