1964 Cowl Vent knobs

[Mike Yager]

My '64 has two cowl vent knobs under the dash with each having a different style knob. The cables and hardware look to be original but I cannot understand why each knob for left and right cowl vents are different. Is this the way they came from the factory? If not, can anyone describe what the correct shape should be?

Thanks.

Re: 1964 Cowl Vent knobs

They should be the same. Likely that one broke as they do when the inside wire cable binds or just wears out. It's hard to describe the differences asthey are very subtle but the original style has a very narrow flat area on the face of the knob at the rim while the repros have a wider rim. Compare it to your rear vent knob which should be the same styleas the front floor vents. The rear one breaks even more frequently due to the long travel of the cable. Hope this helps. David #33277

David:

Thanks, that is a big help. Most likely someone removed a cable assembly from another model year car and put it on my car when the original cable broke. Since my car is a convertible, I don't have the rear vent but will check someone else's '64 for comparison.

I never studied them but the two on my non-air convertible seem to be the same as the rest of the knobs except they are raw black plastic instead of vacuum metallized "chrome". I suspect they all started as black plactic with a certain percentage left that way.
