While looking for a distributor cap I was asked if it were the tall or short type.
What would’ve been original to the 1948? What are the height differences between the two? The one currently on it is roughly 2 inches tall not counting where the plug wires attach. In just several hundred miles the cap wore out where the rotor button contacts the very center coil input. | | | | | Joined: Feb 2004 Posts: 29,771 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,771 | The "high" cap came out in 1955, I believe, with the swap to a 12 volt electrical system. It's not uncommomn for the center button of a distributor cap to deteriorate if metal core spark plug wires are used instead of the string-core resistasnce wire, but that happens over several thousand miles of running, not a few hundred. Check to see if the distributor shaft is wobbling and rubbing the rotor sideways over the center contact.
