Dave, with all due respect, I don't want to take this to a heated point with you. I really don't. Can we Q&A peacefully?
I think I know you well enough to proceed as if your answer is yes.
Are you disputing the fact that my oil cooler was installed on the assembly line just like yours?
(BTW, I totally agree with your last bold type sentence. To me, that makes it all the more rare and valuable. To me.)
