I recently bought a water pump on Amazon...about $57 including shipping, then discovered the same one for about same price on eBay...worth a look. I’m sure you could get from locals up your way - several on this forum should have the parts locally, otherwise @iceton1975 from Berry Motor Group could package it all up and send to you.
Water pump $42.32 including postage here you go - it’s now on sale for even cheaper:
