All I can say is that I agree that the clamp must entail a procedure I couldn't imagine. I was only removing it and had the advantage of being a month earlier/warmer and no rear axle or suspension in the way. I sure hope you did get it sealed.

An engineer was unemployed for a long time. He could not find a job so he opened a medical clinic and puts a sign up outside: “Get your treatment for $500, if not treated get back $1,000.” One doctor thinks this is a good opportunity to earn $1,000 and goes to his clinic.
Doctor: “I have lost taste in my mouth.”
Engineer: “Nurse, please bring medicine from box 22 and put 3 drops in the patient’s mouth.”
Doctor: “This is Gasoline!”
Engineer: “Congratulations! You’ve got your taste back. That will be $500.” The doctor gets annoyed and goes back after a couple of days later to recover his money.
Doctor: “I have lost my memory, I cannot remember anything.”
Engineer: “Nurse, please bring medicine from box 22 and put 3 drops in the patient’s mouth.”
Doctor: “But that is Gasoline!”
Engineer: “Congratulations! You’ve got your memory back. That will be $500.” The doctor leaves angrily and comes back after several more days.
Doctor: “My eyesight has become weak.”
Engineer: “Well, I don’t have any medicine for this. Take this $1,000.”
Doctor: “But this is $500…”
Engineer: “Congratulations! You got your vision back! That will be $500.”
