Oil pump.... reuse or buy new?

AS with new cylinder heads new oil pumps have to be pulled apart and inspected
best to round the corners and to check and see if the passages line up
I've found all kinds of grinder crap in new pumps
and there is a lot of junk out there
remember that the size and flow of the intake side is very important, more important than the pressure side
oiling of Mopars from one to the other is critical
