I took the day off work Friday and took it all apart. I had Matt order the
Evap core for me just to be safe but we ended up not needing it. The one in
there looked pristine.

It only took me about 7 hours to do the job, and that's including the extra
time I had to remove the dash because I "lost" a groundwire, as well as the
extra time I had to take to re-center the clockspring (I didn't pay attention
and managed to spin the wheel completely around a few times). I could
probably tackle it in under 6 hours next time though. Thusfar I haven't
noticed any rattles or anything besides a slight coolant smell. We pressure
tested the new core though so it's just old coolant burning off.

I will say that this new core is MUCH nicer than the one it replaced. The
stock Dodge part was about a half-inch thick and maybe 12x6. The new one is
slightly smaller but it's almost 2 inches thick. It seems to be able to
deliver warm air in about 10 minutes, and at full operating temp will output
air in the 130 - 150 degree range out of the vents. Needless to say it gets
very warm in the cab now.
