8 1/4 rear disks

It did not even come close to fitting. The vendor was a pain in the *** and had to eat shipping both ways. Sorry for the late reply, just stumbled across the thread. I ended up using the jeep Cherokee setup and anyone that says you wont notice a difference should drive this one. I did a build thread and need to find it and post a link. I have a little over 300 into the whole set up and it stops better than my Cobalt SS daily driver with slotted rotors. The only thing I need to add to the build thread is that I did end up using and adj prop valve, made a huge difference.

Found the link here it is. http://www.forabodiesonly.com/mopar/showthread.php?t=301415

Joey might be a good build thread!
