    Ditto on Dale's seals I got some from him as well and they are perfect fit you do not have to trim anything.

    The seal Dale Cooper sells is a much better fit than the Mopar seal (National P/N 5414 or Felpro kit BS 40245). The Mopar seal needs to be trimmed about 3/32" on one end of each half to fit. What makes this a challenge is that there is a steel reinforcement ring buried in the rubber. You have to carefully trim the rubber around the end of that ring, then spend some quality time with a mill file or grinding wheel to trim the steel back flush. It's better than the rope seal, but it's still a pain. Dale's seal should slide right in.

    Basically Dale trims these down as do we. When you buy over the counter , just cut the ears off and trim with a bench grinder and make sure it sits about 1/16th above the cap and block.
