I wonder why...

the defroster vents in our truck are square, when they were long slits in cars much earlier than 67???

It kinda got me thinking last night when I was peering through a small thawed area in my windshield.

(I guess this is in the right forum, HVAC?)

my dad and i were bumpin' and i noticed we each had a little hole of defrosted windsheild to look through

i wish they had of run a slit down the dash...

oh and what is HVAC?

well that is somethiiing you can add in to your dash. if you dont plan on using a dash pad it woul be easy to convert your dahs to a different duct end. i saw it here on the forums. someone had gotten some dodge rectangle defrost ducts and put them in his dash . i think the reason he used the dodge duct was because he could hook his orginal tubes to the reqtangular vents.

id love to do something like a stip of hot air custom made into the dash next to the windsheild... since im trying to make the 69 the safest bump there is

i would hate to butcher a nice dash though...

i think it was in some of the tutorials i read when i first came on the site. he just cut them in right up next to the windshield.

i found spartmans thread about it which linked to another thread that showed something i would love to do to my 69 which involves cutting and welding, which could easily be dont at my work.

right now im trying to decide if i should do exactly what the bumpsides site guy did

ive been looking at the bumpsides guy's defroster vent and noticed for all that work, it doesnt look that much better.

i wonder what i would be getting myself into if i decided to have my own vents custom welded/bent at work, the old defroster vents sealed up, and run my own tubing to the heater. hmmmmmm

im thinking i could put the vents(maybe each 12 in. long, 1.5 in. wide depending on the room i have) behind where the dash pad would go. hmmmmm

im going to look at the possibilities in my truck... and see if i can get a plan of measurements. it would be easy enough to just get a nice peice of scrap metal, cut it to the right size, bench press it into a rectangular shape, weld it up, create a opening in the bottom of the new vent for some tubing and weld it in the dash.

am i going crazy or should this work!

i was thinking about the idea today and put tape roughly where i wanted the vents. (pictures are taken in the 71, but the vents will go in the 69).

heres my plan drawing. how well would this distribute the air?
what can i improve?

also im not sure the original duct will reach that far, it would be close.
and im thinking that instead of 1 in. height, that it should be 2 maybe for the vent in the picture i made.

also, can someone get me a picture of how much space is between the windsheild and a good quality dash pad(i say this because cal-mustanges were shorter)?

thanks

enough space to loose a pencil in there. the only way to get the pencil out would be with another pencil as a flicking tool. to flick the other pancil out of the hole.

ok so if i do this defroster idea, i will have to weld up all the dash holes and vents etc. since having a dash pad wouldnt be a choice really. saves me money too on a dashpad

1971ford · Post by **1971ford** » Fri Feb 15, 2008 9:26 pm

my dad has approved the idea

and i checked the 71 for an idea of clearance, but it was really hard to see how much room ill have with everything in the 71. im sure it will clear, and if not i can move stuff around in the 69 until it does clear.

im going to try to draw more detailed, better drawings of my plan.

i just made a new topic....
check it out and please let me know of any ways to improve my drawing etc.
