Heater core recommendation needed + another HVAC issue

[Matt B]

I'm nearly ready with putting everything back into place. What a job...
I spent about 2 full days with it, whereas plenty of time went into research as neither the shop manual nor the YouTube videos were very precise in giving instructions.

The only things that were painstaking or complex was to remove the heater hoses and removal and installation of the horizontal tube that is attached to the heater core rear cover. This thing is a nice example of what happens when engineers go to work after a long party night.

Summarizing I can say that the job isn't too complicated but requires patience and a bullet proof way to keep your overview.

Also, I can only recommend to pull the upper dash. It's extra work... But it quickly pays off the further you dig into the guts of your dash.
I can't imagine who the job can be done PROPERLY with the upper dash in place...
