> I plan to pull the heat exchanger core to today and see where that takes
me.

Mark, you'll have the core out in 20 mins.  It's VERY easy to pull.

Here is a link to some pictures on my instagram, should they help.

Couple of caveats.  If you notice on the back side pic, the cup on the
radiator is also connected to the top of the exhaust mixing elbow.  If can
be a *$%^!!!! getting the cup back on both.  Also, the radiator where the
cup connects has a lip, and it can be a little of a challenge getting the
cup properly seated on the lip (especially new cups).  You can lightly
grease the cup so it will slide on better.  Go more sparingly on the front
side cup (very thin layer), and be wary of using silicon based grease on
the front cup.  It can ball up and clog the front side of your heat
exchange unit.

Also, when you begin to slide out the tube, once you start to slide it a
direction, don't let is drop too hard into the radiator on the side of the
tube sliding inward.  Not sure of the strength of the metal on the tube,
don't want you to dent it as it drops.  Also, might want to try and make an
orientation note as to which was the back side and which was the front side
of the tube when you pull it (not the orientation of any writing on the
tube, etc).  Don't know if it matters, but I like to put parts back in as I
find them, and it's easy to lose track.

good luck!
