My racing buddy had the pickup go bad a few years ago at the track in a MSD distributor, but for a 351W. We asked around and found another racer with a spare Ford Motorcraft replacement pickup. We also picked up a replacement pickup for a Ford Duraspark at the local NAPA too. What we found ( going by memory here ) was that, although the pickup is basically the same, the size of the two holes though them ( through the magnet ) and the way the mounting screws go into the distributor body are not the same, and so we weren't able to directly put the Motorcraft pickup in the MSD distributor. I'd have to compare side by side again to remember the details. Someone who is handy could maybe adapt the Duraspark pickup to the MSD. MSD does sell a replacement pickup, you should be able to order from Summit, Jegs, etc. I'm sure some local parts stores that sell MSD products can get one too, but I doubt many carry one on hand. I will add, like Doug's experience, I've been reading about quite a few people with MSD distributor pickup failures the last couple years, although in my friends case he had been wiring on some new electrical devices right before that race weekend, and he may have been responsible for his failure, we don't know for sure.
