Save the money.
The revices white plastic impellar is as good, if not better than, the metal impellar. I have seen more metal styles leak through the shaft area, than I have heard of white failures.
now, either one can come completely loose and freespin, but that's another issue.
Don't jump on the metal impellar bandwagon, just because. You already have the white one purchased, and the car torn apart.. throw it on there.
be done with it.. you'll never have another problem with it.
