I was finishing up a tune up on my warlock and for some reason the new coil to distributor cap wire would not snap into the coil. I checked the old wire and the connector that snapped onto the coil was the sameone that snapped onto the coil. On the new set of wires all the connectors are the same and work fine except wire the coil wire snaps onto the coil.

I bought the new set of spark plug wires direct from Summit and they are the correct ones for a small block dodge v8.

Is the coil just really old (which is why it takes the old style connector that the dustributor cap takes) or did MSD happen to put the connector onto the end ofthe coil to distributor cap wire in the set of sparkplug wires?
