Distributor cap cracked on the way to a show in Portland
Ngl, my 68 Mustang died at a red light on I-5 last Saturday, turned out the cap had a hairline crack that kept killing spark at 2,500 rpm. Swapped it in the parking lot of a Napa for $18, but has anyone else had a modern repop cap fail way faster than the old Motorcraft one?

Did you check the contact points inside the new cap? I've had repops where the brass was paper thin and the spring tension on the center button was weak right out of the box. That hairline crack you found is usually a sign the plastic got cooked or it was dropped before it ever hit the shelf. The old Motorcraft caps had thicker Bakelite and real brass, not this cheap pot metal stuff they pour now. Heat cycles under the hood will split a bad cap in a month, easy. Grab a NOS one off eBay if you can, those things last forever.
