Ebay has both the original (in the $40 plus range) and the repop ($26?)
There are Ebay sellers pricing this up to $67 so check around for a confirmation it is original. IIRC, most of the $40 ones are.
A repop can be bought out of the box from AutoZone in the same $26 price range. Nice as you get to check the fit/form/function. And go elsewhere if not to your satisfaction.
