please help...if it's not one thing it's another....

For future problems, get an in-line spark tester ($4 at Harbor Freight) and put it in-line with the #1 spark plug when you have a problem. It is much simpler and better than trying to hold a spark plug wire near the block. Flashes a neon bulb each spark. If you see flashes and won't start, spray starter fluid down the carb barrel. If it doesn't fire on that, check the timing with a strobe light. You can get timing lights real cheap on craigslist or garage sales since most cars since ~1990's can't use them. Run a ground wire direct to the body of your ignition box (very common problem). As stated, very unlikely you have points in a 1975. Absurd if somebody downgraded to points. The Mopar electronic ignitions are problematic. It is easy, cheap, and better to upgrade to a GM HEI module and coil. Many posts on that.

Main thing is you need some simple diagnostics tools that cost <$20 total. I carry a kit in all my cars w/ alligator jumper clips, spark tester, starter fluid, ... It has saved me from a tow in several cars and gotten us back on the road in 5 minutes. As TrailBeast suggested, I hot-wired the coil after I bought my 64 Valiant slant to drive it home (ignition switch problem).
