Hello all, I'm in need of some help with my 1954 GMC 248 six. Where can I find a replacement water pump for this engine or will one off of a 235 Chevy interchange? I did find a rebuilt pump but its priced at $300 bucks and I don't want to pay that I'm sure there is a cheaper alternative. I did a search but this topic is a bit limited and a bit outdated. Any info is appreciated.
