THanks! I'll add that to Wilton's instruction.

There are a few mistakes in the service manual procedures that slowed me
down a bit.
The glove box must be removed to disconnect the right front speaker, the
small suction motor for the interior temp. sensor, and the light for the
vent control. Removing the glove box (or the airbag on later models) is
not even discussed.
Toward the end of the heater box take-apart, second to last step (or there
abouts) says remove some fasteners and then pull off top piece to expose
the evap, but the next step says to remove more fasteners, that second step
needs to be completed to pull off the top piece.
In order to get at the expansion valve, the cowling ductwork at the bottom
of the windscreen needs to be removed, that step is also omitted.
I used a bunch of small ziploc bags, labeled with each assembly, to hold
all the fasteners for those assemblies, that kept all the assorted nuts and
screws in order.
The most troublesome connectors were little plastic pins with a
four-cornered push-snap connection, usually very awkwardly placed, that
hold the various vacuum pod arms to the levers they move. I'm sure there
is some special tool that makes removal easy, but I don't have it.
I used plumber's putty to substitute the factory seal between the heater
box and the body (hole in the firewall), which was very similar (still
somewhat malleable after 32 years).
