05' Rubicon

That's a new one on me. I've never heard of 'medium gray' for a soft top color. Good luck calling Sierra Top for matching windows.
My 05 lists the same.

I called sierra and they did not have medium grey and the lady I spoke with wasn't familiar with the color also. This might really be a unicorn lol
 
One of my favorite mods so far I forgot to mention was the addition of the Flowmaster super 44 muffler. Holy cow the tone it makes it awesome. Highly recommended.
I was thinking about getting the same muffler for my tjr. Did you have any issues installing it? I was wondering if I would have to weld it in or just clamp it in
