I would agree. Timberview seems to have done most of the right things, but no mention of checking the spark. He needs to flick the points and make sure there is a 1/4-to-3/8-inch white/blue spark out of the coil. Then make sure there is the same spark from a plug wire to ground when cranking, and then pull a plug and check there. If there isn't a good spark when cranking the starter is dropping the voltage too much which would indicate poor battery and ground connections. They need to be cleaned and tightened. I also wouldn't trust the braided cable to frame connection, especially with the car setting so long. I had that problem with my car even though it had been starting ok. I ran a new cable directly from the battery to the engine block.
