Does anybody know if they made a few different water pumps for the d1005? I had a cracked timing cover, found a used one, put it on and everything is exactly the same until I went to swap the water pump. Everything lined up except one bolt. The hole is off by maybe 1/16-1/8 inch. I’m afraid to go drilling and tapping as it was hard to find a cover. Especially if it isn’t necessary. The original cover was on my 96 b2100, not sure what the donor is on the other cover. Any knowledge is appreciated.
