I ran a Unilite on my '69 Cougar many years ago. My Unilite had a vacuum advance, but likely that's the only difference. It came with a "degree key". I was a plastic key with stepped notches on it. You would insert it into the distributor for setting the curve. Can't remember much more, but FYI, you can change the ignition curve on a Unilite pretty easily.
Otherwise, it's the same as any other distributor. Keep advancing a few degrees at a time. When it starts to ping, back it off two degrees and you're there. (Some light pinging during a test drive won't destroy the engine.)
