Tinster, if I read everything correctly, you've got more parts on order. I tend to agree with Brosky and others about those wire and connections in the distributor. I don't quite feel comfortable with the appearance of your ground wires on the base plate, nor with the appearance of that plastic insulating block on the back of the distributor, nor with the appearance of the connection made at the points of that negative wire from the plastic block.
Your base plate wire seems to go beyond the plate connection point,then bend sharply back. I may be seeing it wrong, but something doesn't look clean and neat there. Also, I can't quite tell, but that negative current wire from the plastic slide block appears either burnt or sooty at the points connection.
Maybe I need to re-read your posts, but did you confirm you always have current to the + side of the coil? There are two ways to lose current there. One is a bad connection that goes "on and off" at the distributor. Crimp connections in my opinion should be minimized or not used. Some people will always solder and heat shrink. (that's what I did to a neighbor's cat that was bothering us)
Now, if you want to think "outside the box", what about checking the connection at your ignition key? Hopefully, nothing is burnt or bad there. Be sure to disconnect the battery before messing around behind the dash. It is fun back there, and maybe you've been there already. A bad wire at or near the ignition would do the same thing as a bad wire at the + coil terminal.
I wish I could fly out to see it and help, but that storm would probably stop me. Good luck.
