Yea, get to work! Someone needs to.
On occasion when we have guests my wife will volunteer me to give them a ride in my 911. Most people have never gone around a corner at a rapid speed. We have some fun (for my 911) interstate on-ramps. One is a very tight S curve that blends into a 70 MPH speed limit.
My wife's cousin and her husband came to visit, and he was talked into a ride. He is part Sasquatch, and has size 16 feet! He is 6'4 as well. He was wearing his custom made boots and squeezed into the passenger seat. Anyway at some point as I was having fun just merging onto the interstate, his giant boots squashed the cardboard hose for the AC vents. He was properly terrified and was sure we would roll over. I did compensate for his large mass and did not push too had in the on-ramp. I did not know about the crushed hose until months later when I was was doing some work on that side.
Crap, it is a 36mm cardboard with a foil liner to stand up to the roasting hot heater, and the AC cold. No plastic hose will stand up to it, and so one sells a hose that size anyway.
I searched through the parts catalog from Porsche and finally found 911-573-204-00-OEM. Pelican sells it in 1000 mm long pieces for only $12.75. So ordered it from Pelican. I will need to get that replaced before my trip to California. It should be fairly easy.
