The original core support was rusted through in a couple of spots near the battery tray so I ordered a new one a couple months ago. Now that the engine is back in I got the chance to mock it up with the radiator and electric fans that Dad had purchased. Found a few conflicts and I made some mounts to adapt the shroud to the radiator. I also had to drill out the spot welded lower radiator saddles and recycle them to the new core support. Looks like the new core support was set up for a 3 core radiator where this truck has a 4 core.
I made some reliefs on the lower corners of the shroud where the bottom radiator saddles where hitting it and changed location of the fan circuits so they existed the shroud closer to where I plan to mount the relays.
Radiator and fans painted and installed. Now I'm into wiring.
