I used FatMat for the road noise and insulation. This FatMat stuff went on pretty easy as long as I first recreated a template with cardboard. I was able to do the entire cockpit with one roll. 
While I was at it I took the brake pedal off and at a local machine shop used a hydraulic press to give me a little more room between the gas and brake pedal. I also decided to replace the brake line hose from the rear end to the chassis. I had the stock hose and thought it best if I replace it with a new hose.
While the body was off I also decided to put in a new radiator. At first I bought a new heavy duty Mustang stock radiator but I did not like the way it mounts. It hangs from the top rail which was not secured to the side tanks. 
So I bought the FFR aluminum radiator and a new aluminum shroud from ffmetal.com. I did have to find a new upper radiator hose since this radiator had a larger inlet (1-1/2 inches). I used a Gates #22227 if anyone is interested. It is 1-1/2 inches on one end and 1-1/4 on the other which is what I needed.
I finally got around to installing the carpet. There are so many pieces it was like a giant jigsaw puzzle. Hint: Look in the installation manual to see a picture of all the piece and where they go. That was very helpful. 
A lot of folks complained about the quality of the carpet. But for me it is good for starters. Maybe some day I will put in tile. 🙂 I’ll need to find a bezel for around the e-brake. The one I ordered from Finish Line was not for the stock Mustang e-brake.
Got a call from the paint shop… the body should be done in a couple of weeks.
Hours spent on the build: 331 hours
