Im trying to find a SP901 plunger spring for a PSB6A hydraulic head assembly. The SP901 is the AMBAC part number. Who has some spare parts I can buy. I tried to call my local pump re builders and it seems like no one can come up with what im looking for. Im in central MO.

Sadly PSB units have been obsolete for a several decades, AMBAC will barely admit to having ever built them and has produced zero parts for as long. Unless can find a old pump for parts may be out of luck.
