Spark plug wires:
Got one of the sets advertised for a 69 SB and Pertronix compatible. Even though I laid them out and tried to match each wire to a cylinder, I am not really happy with those precut wires. For a more satisfying result, next time I gonna cut and crimp the spark plug wires by myself. For now, I leave them as they are.
With the spark plug wires installed, the engine compartment starts to look more complete again.
