Sometimes Google search has flashes of former genius. While randomly just searching the part looking for something else, it served me an eBay listing for a completely different part number, but the pictures were of the right part. The only reference to the proper part number was very faded sticker on the corner of a box, with the main number on the big label was even hand written over in sharpie. Figured it was worth the dice roll, and won a brand new part.
