Cleaned up and repainted the heater core box.
My heater box had a break in it, probably from a socket on a PO's spark plug replacement, my spare one from the parts car had a bigger break in the same place so I just put a piece of foil HVAC tape on the inside until I can find a good replacement (didn't feel like getting into fiberglass repair right now, this is taking TOO long as it is!)
Also put new foam on the diverter. It could stand being a bit thicker, I'll probably replace it with something better in the future.
After getting the heater core in I got the Y pipe bolted in and got it fired up! Started up fairly easily (thankfully!) I still need to get the drive shaft back in and clean up the wiring (new split loom) but I am so looking forward to the test drive!
