Summary: Had to redrill 3 of the 4 mounting holes so it would bolt to the block. Had to redrill the alternator mounting holes cause it was crooked and the power steering hole threaded and should have a hole all the way through has to drill that out also. Took on and off 5 times. Not Worth it buy a usa made pump for more money or a cast iron water pump....
No, I would not recommend this product.
