Alignment and sizing was correct

Summary: The fit was correct straight out of the box without any issues. Belts were tight but installation was not difficult by leaving pump bolts loose and then installing the pully with belts already on the pulley as I slid it on. After a brief run period the belts seemed to normalize and were tight but did have the expected give in them. I do not expect premature water pump bearing failure.
Yes, I recommend this product.
Product is great ran same pulleys for years..
