This water pump came off of a '63 421. Notice it only has 3 gussets that extend from the base to the hub. This one fits a '63 389. The part number ends in 677, the rest is hard to read. Didn't see one like this in all of the picture travels. Can someone measure the distance on ones that we agree will work on a V8 from the back of the cast base (that touches the timing cover) to the front edge of the hub? It should be 2 7/8" or 3"
