Any other opinions? things to look out for?

How level does the bracket need to be? if it's rotated a few degrees from how it sits now, as long as the caliper bleeder is highest part of the caliper, and the bracket for the parking brake cable line up...is that all I need to look out for?

I spec'd out a Durango rotor and it's 1 Cm thinner than the Dakota rotor, (but none were in stock) if the parking brake hub is the same diameter, just not as deep, it MIGHT be enough to get it to seat on the axle flange, and clear the rear dust cover--if so, and the caliper still has room to slide, would that work out ok, or should I stick to grinding and re-welding? (i'm just not looking forward to grinding on that weld...it's probably hard as a rock, and I'm worried that my angle grinder could eat into the tube or flange a little bit as I try to get all of the weld removed.
