Someone put the wrong distributor in this 273...but it works!

THIS IS WHY auto parts are so currently AFU. "Back in the day" we PREFERRED dist. tag numbers. You just looked the number up in the ignition book, Wells, AC/ Delco, Standard, whatever, and there were the parts numbers for the replacement parts. Just Like That. Used to take me all of 30 seconds to find a dist number "in the book."
