Thanks Mike for the positive support.
As I am currently in Canada and drive out Saturday to Florida with my car, I'll get a jobber one installed locally from my service garage-needless to say not Chrysler.
He says he gets them from a local jobber and that it is the very same as the one in the box of M-B. With my Forum reference, he now said he'd sell it to me for C $50...so he may well be in the same supply thread as Joe TLC.
At $19,95, when I arrive in Fl, I'll order another one from Joe TLC and compare to what was installed in Canada before leaving. Even if I never use theone from Joe, I'll still be "in the money" vs $650.
Thanks,

very happy indeeed
