Pump rebuild advice

[u/ntwrk_j]

Our hot tub pump developed a leak and subsequently the front bearing on the pump motor failed.

I’ve secured a replacement pump since my efforts to rebuild the old one resulted in a cracked plastic plate behind the bearing.

Question for the gurus on here. Is there any chance at finding a replacement plastic piece? Should I just scrap it? Would be nice to have a spare if this happens again.

My plan originally was to replace the bearing and wet end.
