AC vent below dash

Back in the day when I worked at the dealer, I was called "The Weasel" because I could change cluster lights without pulling the cluster.
Small hands and wrists did me in. I got all that crap back then.
I would rather do 318 with A/C water pumps than mess with some of that stuff.
After the senior mechanics tried for the better part of a day to find a thunk in the rear of a brand new New Yorker they called me. 1 hour later I told the service manager that I found the problem. He looked at me in disbelief so I pointed to the problem area. Somebody had failed to place a bushing in the front spring eye on the right rear spring!! I spent 45 minutes in the trunk as the porter drove me around town. And they wonder why Mopar had a crappy qaulity reputation.
