Russ,
You're right, that's a confusing setup. Does the slot into which your lower
center vents attach appear to be a factory-cut opening? I'm not familiar
with '73-'74 so it may be OEM. Seems to me I saw somewhere that there was a
factory retrofit to install those center vents like the 75-76 coaches have;
and I'm pretty sure Golby advertised them at one time.
If you can't see the Max Air door through that opening, or the A/C
evaporator which it conceals, the back wall of the HVAC box has not been
modified and is still blocking the Max Air flow. Frankly, it seems to me
too complex a modification to consider. If that opening is actually serving
as a return air duct, it won't do you any good to open the hole behind the
glove box into the fresh air plenum -- that opening would only augment what
you've got.
I've got the Type II HVAC box I removed from my '76 setting on an outside
workbench. I can take and post pictures tomorrow if it will help. In fact,
if you want to pay shipping, the box is yours.

Is it worth it to replace a 73 Air conditioning dash unit with a later model or is the updates Jim K offers enough. And are the updates just parts from the later models?
