I put the fuel tank and line in today, that was a pain in the butt, but I finally got it in there.

I also put the heater box housing and I drilled the holes needed for the heater hose lines, then I put the core in and somehow got the lower heater hose connected, the hose clamp is on the inside, it's a real hassle but without the transmission tunnel in position I can get to the clamp, basically I put the hose thru the firewall a couple feet, then I put the clamp over the hose, then I connected the hose to the core, then I put the core in the heater box feeding the extra hose out into the engine compartment, then I tightened the clamp, that hose is around 6" long and goes to a valve on the head, the upper core outlet comes out thru the firewall so I connected that hose with a 90 degree turn towards the left and that hose goes to the water pump.
The heater housing and core in position.

The engine side where the hoses come out the new holes, the top hose making a sharp turn left behind the engine.

Here is the freshly painted face of the heater box, I have stickers for it, I will need to find them to put them on.

Tomorrow after I do a job I will likely put the stickers on the face cover and install it and install the boot coming from the air inlet housing.
