Bearing it self will be good in a 50 or 60 year old NOS kit but
I wouldn't count on the seal still holding water or the grease
not being dried out and those are as I mentioned earlier,
sealed bearings.
Someone is making the bearings and seals cuz they are still
selling rebuilt and new water pumps for our trucks. Finding the
source for new fresh parts is the kicker.
