Beefy 3/8" thick differential cover fits the full float 14 bolt axles and will mate up fine with your ribbed 14 bolt axle. However, the additional bolt kit that we sell WILL NOT work with the Ribbed style 14 bolt. You will need to reuse your factory bolts (if they are long enough) or purchase new metric bolts with thread pitch (M8 X 1.25)
