Working on Water pump on 99 Sentra. Seems everything that could go wrong has gone wrong on this project. I need to find OEM part number for the bolt that holds two "crossbars" of the drive pulley adjuster bracket together. NOTE: "adjuster bracket" is my own name for the part. It is the bracket that the adjuster (or tensioner?) for the drive pulley connects to. The bolt I need is in the middle area directly below the water pump pulley. I believe it is about 4 inches long. I haven't been able to find a name for it, let alone a part number. It's gone missing and I need it to put the car back together. it is either a 12mm or 14mm. ANY help finding the name or part number of this bolt is very much appreciated.
