I did the front 11s on my Challenger not too long ago. The big lesson learned for me is to keep a keen eye in the spec for the inner diameter of the drums. Most of the new ones I found were already at the discard diameter brand new. I finally found a pair that weren't. I think Napa made some that were good at the time and I believe Raybestos did too, but most were from the same Chinese manufacturer in different boxes. Just double check the specs before you use them. Also the front wheel cylinders by some suppliers don't like fitting right so double check those too before you get too deep in your project. And lastly even with the new automatic adjusters I don't get them adjusting automatically. They seemed to install and fit fine, but I've still had to get under the car a few times to tweak them. That driving in reverse and hitting the brakes hard just doesn't seem to cut it for my car but you get used to living with that eventually.
