Nope, one cap fits 'em all, pretty much. Don' *** me about "which brand" because the bastards that sell 'em keep changin stuff. Blue Streak used to be great, but I hear lately that they are in the dumps, too.
Maybe you got the wires switch, broke the rotor, or just got a poorly made cap.
Did you do ANYTHING else, like play with or remove the distributor? Might have broken the plastic drive gear?
