'67 AC duct work to vent mechanism clamp?

My early '67 has the Witek clamps on the outlet housing. The AIM shows these in C60 A5 as 9414040 clamp. Don

I saw that one, singular clamp in the AIM, UPC 60, A5 for the right hand side duct. That's the only one mentioned in UPC 60. These hoses don't move around much and with the designed in "tang" I can't see the General spending the extra money for unnecessary clamps.

So based on the AIM, there should be one strap band on the most forward hose connection, but the other visible two do not have these same clamps. Any other thoughts out there? Thanks for everyones contributions to my question.

Leif,
The AIM sheet I was referencing is the one Don provided. That is the left outlet, the right outlet is connected by the band clamp pictured just above in the illustration.
Garry,
I agree there are no clamps on the center outlet hoses, the molded in barbs retain the hoses.
I am not sure now whether the left outlet hose should have one or two clamps. I look forward to learning more.
Kind regards

Peter,
The AIM page (A5) that Don provided is for the right side assembly showing a singular clamp. The AIM page for the left side assembly does not show any clamps. The AIM page that I provided (A3) shows no clamps, either.

Leif,
You are correct the illustration is for the right side duct. The view "B" has to be for the left duct as that is the only location with that short style hose.
Kind regards.

No sir. That entire page A5 is dedicated to the RH outlet, duct and grill. Note the content box in the lower left hand corner of the AIM sheet in both Don's A5 posting and my A3 posting. A3 is center outlet, hose and connector. A4 (pictured below) shows the LH outlet duct. Again, only the singular clamp mentioned on page A5 for the RH outlet duct to selector assembly.

Hi Guys,

In all of my years of researching correct midyear AC parts I've only ever seen two separate clamps installed on left, center and right plastic outlet ducts.

The right side/passenger duct has the wide metal "D" clamp that attaches the distributor assembly "pan" to the outlet duct. I found out later in life that the '67 has a unique 1-15/16" inch long "dimpled RBW" hex head screw there where earlier years used a plain 1/2" inch long hex head screw.

The center dash outlet duct has two smaller fabric hoses that slip onto the tines molded into the plastic outlet. No clamps were used there.

The left side/driver's duct uses only one metal strap tower clamp that holds the larger crimped fabric hose to the driver's plastic outlet duct. The other end of this fabric hose shown here in "View B" simply slides onto the left outlet of the distributor assembly. For some reason "View B" refers to this end as the "Selector Asm". When I bought my '66 way back my hose actually could've used an extra clamp there since is was barely holding on.

Here's some photos of my good friend's '67 AC L36. It's VIN number is 14,039. He just told me it's OK to post that. We've shared lots of info back and forth and my knowledge of '67 AC cars has grown considerably thanks to him. Hope these closeups help this discussion.

By the way, there's a guy on eBay right now with one of these #9414040 metal strap clamps for sale. Don't know him. He's not giving it away. But these are very difficult to find. Mike

Leif,
I will respectfully disagree. I am not going to worry about, perhaps I am wrong.
Kind regards

I would definitely say View B is a view from the front looking towards the rear. It is as if you were sitting on the accelerator pedal looking to the rear of the car. Definitely left side.

Re: '67 AC duct work to vent mechanism clamp?

Guys,

For whatever reason, the "General" decided to place View B drawing on sheet A5 when it actually should've been placed on sheet A4. Apparently there just wasn't enough room to show it on sheet A4. But look in the upper center area of A4 and find the View B arrow. It clearly points to the left AC duct which is part #1 drawn on View B. Mike

Re: '67 AC duct work to vent mechanism clamp?

I was able to confirm with the owner of a Duntov cat that he has one clamp at the front most hose end, but no clamp on either the other end or the end going into the center vent. This seems to be the general consensus.

Here are pictures of my AC duct first time posting sorry for doubles. first time I have ever posted. I feel the barbs on the other connections.

Bill, those are great photos. Thanks for the contribution to this thread.
