Well, I tried the parts store route and of course, not right after waiting days for a new core. Looks to have correct bent tubes but is overall much smaller then the one I’m trying to replace and clips won’t even come close to holding it in heater box, I’ll try Ames or finding a place to resolder the one I had.

I ended up installing engine, because I was sick of waiting for a core, but I should be able to just hook the hose from Waterpump directly to the nipple on back of head and bypass heater core so I can drive it for the time being, correct?
