Thank you so much! I would greatly appreciate that.

Never seen metal ones....have seen both black and yellowed white plastic ones.
This is obviously not factory.
Passenger side removed -- complete with two pencils and some debris. Haven't looked closely at the drivers side yet, but I will and post info if needed..
It is made of thin aluminum sheeting and 2" OD galvanized downspout.
Looks simple to make with a hammer, some tin snips, a two by four, pop rivets, and maybe a hole saw.
It measures:
2-1/4" Tall – no more or it won't fit above the glove box lip.
1-1/4" Deep – front to back.
9-1/2" Wide – side to side.
10-3/8" OC mounting holes
1" Mounting tabs
1-3/4" long inlet pipe.
2" OD pipe
Notice the outboard mounting hole is slotted allowing it to be rotated into place above the glove box lip.
It could use some sort of seal on the open side where it comes up against the dash and at the inlet. Other than that I'm sure it will pass as much air as a stock one.

They are very different !! But for the metal ones ... the 2" pipe pointing the front of the truck ?? The plastic ones were pointing downward ... for the metal ones , you must at least need a 90 degree elbow ... but do you have enought place for that ?? Are they factory using flexibles from those vents to the heater ??
The metal ones I saw looked very much like the plastic ones shown in an earlier post.
The one that Amphi posted is the idea I had, but a little more of the angle downward like the stock one. I also was considering welding them rather than riveting.
I will get to work on a prototype off those measurements, and see what I come up with, how long it will take to make, and what the cost of materials will run. I'll keep everyone posted as soon as I come up with something.
As posted earlier in this thread, I used two wet-dry vac nozzles from Home Depot. As I recall, they were around two bucks each. They fit the opening in the dash almost perfect and had the perfect bend to accommodate the flexible ducting. Two machine screws and nuts to attach it.
For the ducting, I used some VW heater duct from NAPA Auto parts. Wet dry vac hose would work as well, but it cost a few bucks more.
I finished the whole project in just about an hour including getting the stuff.
This modification for the defroster was just about the easiest modification that can be done for less than $10
i"ll take a look at my local home depot .... don't know if they have the same stuffs up here but with the dimension i may find something .... will let you know by this weekend if i found anything.
