When did your ignition module fail?

The orange boxes have been crap for well over 10 years now. I never had one totally fail that left me somewhere, but I've had several that would start causing misfires and timing issues at RPM's over about 4k. Below that they would work mostly ok. Upgraded to chrome boxes, no problems. I'd either buy a Mopar chrome box or something from FBO FBO Ignition, Distributor tuning and Carburetion Professionals, FBO Ignition systems, Ford Ignition, Mopar Ignition, Ford Distributors, Mopar Distributors, Ford distributor curving, Mopar distributor curving, HEI Ignition, MSD ignition tuning,. Using anything from Mopar, even a chrome box, and I'd carry a spare just in case.
