No such thing as a faulty component which would cause it to hit. WE've sold 10,000 components and never encountered one with incorrect dimensions. Having sorted out a gazillion caps and rotors I realized the the designs since the mid-30's are quite ingenious. Caps have a certain mounting diameter anda keyway so you can't install the wrong one on your distributor. Rotors have keyways and other dimensions that do the same. Autolite, Delco, Motorcraft etc either collaborated or watched closely.

Perhaps you did not install the cap on straight, but then the clips may not reach the detents. The cap or rotor should have indication of interference.
