What of this can go?

So pulling some weight out of my Civic for my XS build. The A/C system is gone from under the hood but I have the dash out and no sure what I can keep to keep heat and what can go.

Evap core

One nice thing about a lot of older Japanese cars, the A/C was engineered to be separate, so they could ship cars without it and install it at port of entry.

The heater box and all of the blend/vent controls are in the center, the blower assembly and recirc door are off to the right, the evaporator is in a separate unit between the two.  Looks like it can be removed without disconnecting anything else.

 You'd just need to fab a way to connect the two.  The cheap/no-effort option is to remove the evaporator core, tape the holes shut, and reinstall the empty case.  The clean option is to install a non-A/C duct.  Probably not very easy to find now, but I bet there were piles of them in dumpsters when the cars were new.  (My employer was a Honda tech at the time.  He said they usually needed an hour to install air conditioning.  They had a lot of practice)

edit: It's available!

$65 though.

Where are you seeing it available? Everywhere I see says discontinued. It seems to be this part number 79810-SR3-A01

In reply to 93EXCivic :

I did a search for civic non A/C duct and that came up and it said "in stock".

I click the full link and it said discontinued. 

My non A/C RX-7 just has the evaporator removed and the evap holes taped over.  Really, the box is just a slightly bulkier version of the non A/C duct (it looks remarkably similar to the Honda part), the difference in weight is an ounce or two of plastic.

Cool. I'll pull it out this weekend and gut it.
