1957 Plymouth Six Plaza Savoy Belvedere A E A Tune-Up System Vintage PL-54 Tune Up System by AEA American Electric Association 8.5" x 11.0" tune up system chart printed on thick colored stock with invaluable information. On one double sided chart information; engine specs, ignition coil, resistor, condenser, spark plugs, gap, idle speed, ignition timing, ignition advance, distributor, vacuum, generators, regulators, charging circuit, fuel pump and other information, all easily legible and a wealth of information. Also all applicable original OEM part numbers are referenced. All are completely legible and original, not re-prints. Besides being a wealth of great information, they are also very "cool"! If you own or restore one of these vehicles you don't want to be without your car's chart.
There is some yellowing of the card stock and light shelf and shop wear/use.
