This 14 bolt 10 1/2-inch differential cover uses 12 of the 14 bolts. The bolt hole at the bottom was removed because the drain boss is best located there. At the top of the cover another bolt hole was removed. The flange is 3/8-inch thick and blanchard ground to be flat and smooth.We have sold many of these and have never had a problem with leaking. The flange is very strong and the 2 bolts left out are not missed.
Please check and order the correct mounting bolt thread diameter. These differentials were made with 3/8-inch (.375) and 8mm (.315) bolts. PML offers the cover in both versions: P/N 9369-1 is for 3/8-inch bolts and P/N 9369-2 is for 8mm bolts.
