dash conversion non ac to ac - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hensonjd · 06-17-2009, 10:20 PM

I have a non ac cab that is in really good shape and a ac cab that is in horrible shape. Can I put the ac dash in the non ac cab?

Yullose · 06-17-2009, 10:58 PM

Funny you ask...

I'm gutting two cabs right now... one is a '72 AC cab, one is not ('67).

I was going to swap the AC dash into the '67... but noticed it's welded all the way across the base of the windshield. I even buzzed the bolts out of each end of the dash, hoping it might pull apart, but no such luck. You would need to pull the windshield and drill out all the spot welds holding the dash to the cowl panel...

It's not that complicated, but looks to be more trouble than it's worth.

I've since decided to scrap my plans to put the '72 AC parts in the '67... and will just roll the windows down instead.

It really isn't that hard if you have a welder. I am in the process of swaping dashes because my old dash was beat up pretty bad. You just have to pull the windshield out and drill out all the spot welds and remove the bolts under the dash on each side it and comes right out. Bolt the new dash in and weld up the lip under the windshield. I have seen people cut the holes in the dash for the a/c vents also, so that is another option you have.

Don't forget the firewalls are different as well for a air cab. Trevor

Would it be easier just to go with a vintage air system than try to conver it over to stock look?

How much different are they? I planned on putting an a/c dash in my 67 when I get around to restoring it. This might put a stop to that idea.

hensonjd · 06-18-2009, 12:11 AM

Also. How do you get a title for one of our trucks if you dont have one. My trucks cab doesnt have a vin number but it is in great shape. The PO said he got it out of a wrecking yard.

Not that different just need to fill in 1 one and cut it out for the ac set up

You can also split the dash at the holes under the dash pad and weld in the new one, which was cut in the same spot.

I'm using an old air underdash unit in my non-A/C cab. I shaved the firewall, and then cut holes in the dash for the stock style of A/C outlets.

14U2NV · 06-18-2009, 01:54 PM

Not my picture, sorry if it's yours. But you would cut it right where I have it marked. Should be fairly straight forward and your weld seam would be covered by the dash pad.

This would be one of the easiest of the swap dashes. Or you could just cut three vent holes into your existing dash. That's real simple.

For the firewall, just cut out the openings of the A/C cab as one unit and graft it onto the non A/C cab.

Blue71LWB · 06-18-2009, 02:55 PM

would it be possible to graft in the vents ?

**john** · 06-18-2009, 03:16 PM

I cut the factory vents in my dash. Only took 1-1/2 hrs including cleanup. I have the templates for the vents I can send to you. If interested PM me your mailing address.

69sixpackbee · 06-18-2009, 04:17 PM

I did my '72. It was easy. Just cut the holes for the ball and center vents and I went to the local junk yard and cut the A/C firewall al around where the assembly goes onto the truck and just grafted it on with sealant and pop-rivets.
Took about two hrs. Then I just added all of the rest of the parts, i.e, fresh air "flapper" in the cowl, vacuum actuators, etc., etc. No one could even tell it started life as a non-A/C truck!
