i took a donor interior from another truck which had no ac but did have floor vents. my current 87 2wd has no floor vents. after examining around the inner fender area i was questioning where the air inlet would be. are there any different pieces or modifications that i will need to make for the retrofit?
thank you
-
i know in my 79 it has ac and i have found leaves on the passengers side vent also the blower is right there so i assume the vent is vented from the cowl and all the trucks have it
-
the set up seems ambiguous. inside the cab the vents (the doors that you pull open or closed with the lever) are not on my 87. but if i do install the vents from the donor truck i still can' t figure out where the air ducts that supply the air are. like irish said are these included on all trucks?

On my non a/c cab there is a 1" opening at the bottom of the firewall piece where it is attached to the A pillar. You can't see it with the fender on the truck.
-
yes-
i wonder if that particular opening is there on all cabs regardless of the interior having vents?
-
That lower hole is the drain for the cowl. All outside air is supplied through the cowl no matter if AC or not.

That makes sense Blazin. I looked at it never thought of the top...haha
