I closed the hole around the shifter this weekend. Cut a 12” x 8” piece of 16 gauge and used what I had to “form it” to fit. I had to raise a circular area around the shifter hole for clearance with the top of the transmission which was a little tricky. While I was working the sheet I remembered a small shifter boot I bought 10 years ago and thought it might fit as a “sub boot” under the actual shifter boot. I dug it out and sure enough it’s the perfect size. This quieted the noise level tremendously and will look really good when the floor covering goes back in.
