Someone put the wrong distributor in this 273...but it works!
Looks like an old Filko book. I found quite a few IBP series with the 4003 number. The AA narrows it down. Too late and the catalog is too far away to mess with it tonight. It's not the right one for the car/engine regardless of what it came out of. It should have a standard aluminum housing single point. Chrysler built.
