I'm not giving specific deminsions, as with the single adjuster any movement effects both sides. I wound up useing my .100 spacers, but no gaskets, only gear oil rtv. Worked perfect on drivers side, perfect disk spacing on bracket, but not the pass side. If you look at the bracket above, it has a taper milled into it as the drivers side seemed crooked and disk spacing wasn't great on the back side. I think this might be some tow in the axle housing, as everything seats nicely, and with a litle taper milled in has great disk/bracket spacing.
