Cutting A/C Vent Holes in Dash

[coop34]

Anyone have advice on how to cut out the holes in the dash for the A/C diverter balls for a non a/c dash? (Cutting only once is kind of important here)

Hole saw. 2 1/2" for Vintage Air.

My 69 was a non a/c truck, I put vintage air in the truck, but did not like the cheesy vintage air vents that came with my gen2 kit. I went to a salvage and found a 72 that had factory air, Traced the factory holes with a piece of paper and pen, taped them to my freshly painted dash and very carefully cut them out with a mini air saw.

Im pretty sure you can see a pic of them in my build thread.

magwa - did you use factory vent balls or vintage? Did you cut into the slanted part of the dash at all?

geary - what was cheesey about the vintage vents? I'm starting to think that that would be the easier route, although I already have the factory vents to install.

I just didnt like them.They look and feel cheap. Now several of the aftermarket a/c manufacturers including vintage, make nice vents that you can buy, they are usually pricey.

Well, last time I installed Vintage Air, I used factory vents. But I sort of like the VA vents. Different strokes, I guess. I think the VA vents, while not stockers or "correct", are less obtrusive looking and are a really easy install. No screws, etc. I've seen many broken
vent mounts at the screw holes on originals. As for the VA, the fit is just a hole. And then and come in from the back of the dash with the threaded "collar" to pick up the threads on the vent that you push thru from the front.

I used the VA template that's in the kit for placement at first. Then, I decided to look and feel around the back for the spot that was the most flat but had the most clearance. Basically, it was logical. And, even for me, a no-brainer.

However, I DID learn from the last time I made this cut in a non-air dash to take it easy with the hole saw...use a sharp one, a good drill bit. And, I opted for higher drill speed and lower pressure on the drill. Last time I did this, the hole saw
jumped out of the groove it was cutting and left a little gouge in the dash I had to look at for a while.

This time...slower and smart(er).

I am installing a Oldair unit in my non air truck right now and it came with smaller than factory ball vents.I had to use a 2 1/4" holesaw and it worked out well after i called Oldair to find out how to secure them.I like this unit but the instructions are not in depth enough.

I did this in the last year. I used a hole saw for the diverter balls. I'd have to confirm this but I believe I used a 3" saw. The center vent I cut with a dremmel tool.

will the center vent fit in the ash trash opening???

Steven,

The ash trash is only for trash from ashes.

I guess you can make *anything* fit *anything*. But I'd venture that you're better off cutting the center vent hole where it belongs.....

Then again, if it's about custom, there are some very talented metal magicians reading this that would likely say different...

I use Vintage Air vents in a non-air cab. Never failed,,,,when I went slowly and used the correct tool for the job.

I cut the factory vents in mine. I used hole saw and snips and small grinder.

[stevenfromtexas]

wow!!! you inside looks very nice and clean!!

thank you for the reply.
i don't smoke and can't imagine anybody smoking in these pickups or any car/truck for that matter

thank you again for the pictures. i was curious of the placement of the "ball vents"

Thanks.

I don't smoke either. And no one smokes in my truck (or my car).

But, like I told the guy in the office next to me some years ago, after I followed him home, each of us driving our own car (he just bought a new Jag):

"Jim, America's a great place. A place where a guy that has the dough can buy a fancy car,
and no one can stop him from f*#king it up by smoking in it the first two minutes off of the showroom floor".

I meant it. His car, his money, his lungs.

Dremel, grinder, drill, and hole saw. Not in that order. No coffee. No beer....You'll be good.

I used stock vents too. I traced a real a/c truck dash and went to town. It was hard but the end result was nice. Dremel for the center.

Used a 3" hole saw also- went slow- turned out nice

I made a template from an AC truck then traced to my dash and used a reciprocating body saw. Done in 5 minutes and very easy to control.
