Anytime you swap in a new carrier, you should really check backlash as well. Just swapping over the shims as they came off of the original carrier may get you within specs; but it would be a costly mistake if it didn't. Too tight can burn things up. Too loose results in too much driveline slop and an increased chance of tearing things up because of shockloading. I would also suggest buying new bearings for the carrier and keeping your originals to use as "set up" bearings so the good bearings don't get chewed up taking them on and off to adjust shim placement.
