I've probably sold more than 50 of the pertronix setups with only one failure( it was the coil that burned up the ignitor). They are easy to install and don't require removing the distributor. Just make sure you check the coil for required resistance( thats what burned up the one), check the power wire for voltage( i sometimes go in the harness and eliminate the resisitor wire as wired from the factory) and don't forget to file the distributopr cap to clear the wires. Check the advance weights and springs on the distributor while you have the point plate aprt.
