Disc Brakes for 8 1/4?

94 and up to around 2000 or so Grand Cherokee rear discs will fit the earlier 8.25s if you enlarge the center hole on the caliper adapter/dust shield to fit the earlier 8.25. There are several threads on upgrading to discs. I have a 73 or 74 A Body 8.25 that I will be doing this conversion eventually.
