Make sure you have a coil that will work with electronic ignition. I swapped mine over 2 years ago with an autozoo '73 distributor and black ignition box and a Summit Racing harness. 2 weeks later, the car backfired and died leaving me and my sister (and her kids) stranded on the side of the road. The electronic ignition fried the coil. So me and dad went back to autozoo and got a '73 coil. It's worked fine ever since.
Live and learn.
