It may still be a worthwhile purchase for the components (if you like the price).

The impeller is cast iron and will also fit the cassette-type bearing used in the truck water pumps. Often these impellers are badly corroded and not suitable to re-use, or may be fractured when pulling them off the old bearing.

The Truck bearings are available separately, but kits are hard to come across. By using this kit with a separately purchased bearing, you can rebuild your original pump.

I try to buy any used truck water pumps I can find with good pulleys and impellers, because those bits are hard to find, but the bearings themselves are still a catalog item.
