Problem installing heater core on '72
I am trying to get the heater unit with a new core back in my '72 air car. I removed it from inside after tearing apart the dash. I had such problems getting the old one out that I cut the pipes with a sawzall. Now the heater box hits where the firewall curves over. 
I had to put on the hoses first since they can't be done after it is installed, which makes it more awkward. Has anyone done this before for a 68-77 Vette with A/C? What trick am I missing? I tried going to old threads, but didn't find the info I needed.

OR, you don't have the firewall stud lined up properly.

That's a nasty job that I would not wish to repeat (touch wood!). You can see from my pic that the hoses just have to go over the raised ends of the spouts: about 1" for the clamps to grab. But you have done it now. I am very happy for you!! Hopefully I was of some assistance. That is what the Forum is all about.
