Fresh water pump options

[Lucky enough]

Before I spend 600 bucks on a water pump, does anyone know where I could source the Mitsubishi version? K2AS block. I have scoured the net and I found one in the Netherlands that is 3 or more months out. Surely there has to be more options. The one on the motor has no part numbers to cross and aside from leaking from the weep hole, seems to be in good shape. Is rebuilding an option?
