I think it's better for you to get a donor than to do hotswap on those.

Why don't you forget about P/N and just buy the same model?

Totally agree. PN may be preferable, but in my experience it does not always need to be perfectly matched, in some successful cases there is even no match to PN...

heads don't match. Unlucky guy ?

donnor heads are ok, I back them into donnor drive

Hi,

You should compare it with your donors.
