I bought a 2nd hand but never-installed 2008 factory soft top to put on my 2010 JK. The wind noise at the top of the windshield is deafening above 35 mph. I've had lots of vehicles with soft tops...never anything even close to this noisy. There are no fitment issues. It's had plenty of time in the hot AZ sun to "relax". There's uniform contact at the seal across the windshield top, and no water leaks even with a high pressure hose. I even removed the slight interference of the top frame plastic trim with the footman loop on the 2010. The roar and howling prevents any conversation or listening and if I can't find a solution, the soft top goes.
