I have just been asked this question but the parts lists don't list the differences just different part numbers so there is a difference but what is it?

I've just learned from Don with the e39 group that between and including '97 - '99 the water pumps on the 6's had metal impellers. After that they were/are "improved" plastic.
Does anyone know if these metal impeller water pumps are also on the v-8's?
