To be truthful, the 12v system uses a 6v coil too, but to avoid confusion, I like to go to rockauto.com and order the points, condenser, coil, cap, etc, etc for a 1956 Chevy Truck. That way there is no doubt about you getting the right thing. This is true for any auto parts store you go to. Ask for the ignition parts for a 1956 through 1962 and you will not be disappointed.
