The New, Newer Project: Part Tres...

Once the new core was installed I prestaged the heater housing in the diagonal position and did the reverse move of push one inch, rotate one inch until the whole contraption just locked right into place. You do of course, have to remember to hook up the vacuum lines to the opposite side of the housing when you are halfway through the push and rotate process otherwise you will never be able to attach them once it is installed back in it's final position.
