Stop in for a cup of coffee

And since we are taking Barracuda's a question for the brain trust.
Question concerning the interior heater vent hose.
Question is was there any sort of clamp that held them in place attached at the vent tube??
Mine were attached only at the two vents under the dash next to the heater box. At the top of the dash weren't attached at the vents.
I know why. They used an aftermarket 2" wide hose and but had a 2 1/2" opening on the vent tube at the dash. Wasn't coming close to covering the vent tube.
As usual thanks in advance for any input.
Could have changed between yours and 75...Mine had a small metal clip that went on hose and gripped the plastic. The ones I got from DMT are rubber hoses. not like original fabric over spring. Don't recall if I clamped. Think they fit pretty tight. Another thing- my original had a metal piece on it for driver side to keep it clear of the wiper linkage.
