Re: 62 galaxie 500 heater hoses
I, and some other folks, found out the most popular (auto zone, etc) heater cores said to be "exact fit" were on the small side. I could see the air was just going to pass around the core so I packed foam all around it to block the sidestream. Did not work as hoped but I'm not going back in there again.
Maybe it's just the 65-era cars, just something to watch for.
