How to set breaker points?

First a question. Got a dwell meter?

I'm going to say 'no' since I don't know what that is... this is my first Mopar without Electronic Ignition so I'm in a little over my head at the moment.

Thanks for the link 63dartman!

History: I initially set the points using a Richard Ehrenberg write-up in an old Mopar Action mag. The car fired right up and was able to do the break-in with no issues. I was able to drive the car a few of days after that and it ran great but last Sunday morning it started detonating bad, even at light throttle applications so I brought it home and retarded the timing. In order to get rid of the pinging, I had to retard the distributor so much that the car refused to idle anymore forcing me to raise the idle rpm on the carb. This caused a massive rpm drop when shifting into drive or reverse and the car just stalled when asked to move by my right foot. I have no idea what changed between a nice evening cruise Saturday night and the next morning when it wouldn't move without detonating. I've been screwing with it for 2 days now and I can't seem to find the 'magic' combination of timing and carb to make it run normally again. Anyone have any ideas what might have happened while the car was parked overnight in my garage by itself???
