I didn't realize that the bolts were torque-to-yield, and when I changed my WP I ended up snappd a bolt!
Since I needed the car fixed in a hurry, I just went to the hardware store for a regular replacement bolt, and also bought a torque wrench so I wouldn't overtorque them again!
Havn't had any problems with the non-ford bolt, and I've got ~10k miles on the new water pump.
