Our 1970 Buick Riviera is an all-stock and original ride, and we don't plan on restoring this car anytime soon.   However, we do like driving it, so we elected to install a Pertronix Igniter electronic ignition module and Flame Thrower ignition coil our original distributor to eliminate the mechanical breaker points and enjoy smoother starts and better performance.
