the top 2 are cheap press steel, although they may last, the design will create cavitation, which could cause case erosion.
the back end of the impeller is flat for a reason, this is to prevent cavitation and to help flow through the pump. The small hole in the back of the impeller is there to allow a small amount of water to pass, which would then be on the low pressure side, creating lubrication for the seal. i would not be happy with that part, unless i had no other option..... even then i would insist on changing it out for OEM asap.
if the shaft sizes are the same, you could remove the impeller from the busted one, and fit it to the new one, A small blow torch, and puller should do the job.
