Elec woes, crank, no start after running then parked.

Thanks, I thought ecu etc would need to come out? Round or square back alt?
You just unhook and remove electronic ignition distributor, drop points distributor in, hook black wire from distributor to ground side of coil, done. I had to open the point gap on mine to get it to run good. I also welded up advance slots to limit total timing. But out driving around engine makes a lot of power can't really tell a single point is in there. Now that I have electrical glitches all shaken out can go back to electronic.
Here is one I bought:
