How do I install a register boot in a hard-lid (drywall) ceiling so it sits flush?

Frame the drywall opening using drywall tracking or sheet metal studs matching the exact outer dimensions of the sheet metal register boot. Secure the boot to this rough framing structure above the ceiling level so that the bottom raw edge of the sheet metal collar sits exactly flush with (or \frac{1}{16} inch above) the finished drywall board line.
