Well I figured I'd update this in case anyone was having a hard time falling asleep.
The pipes from the engine bay just wouldn't line up. Someone has been in there before and I guess got things out of wack.
So I cut the ends off the pipes and put them into the heater core and then tightened up the bracket.
Actually much easier to deal with doing it outside the car anyway.
I'll just get some coolant hose and make the connection to the cooling system through the firewall.
