I have a 2008 Wrangler Unlimited JK and I bought a 2015 Smittybuilt extended top 94535f or it. I also bought the 2015 OEM soft top for it too! But I cannot get the extended top to stretch out over the top of my Jeep. Heat doesn't work, the weight from rather large friends of mine doesn't work. I called Smittybuilt to see if the width of the Jeeps were different. I also asked if the "added frame" pieces that I screwed to the Jeep were different from the 2008 to the 2015. They said it's all the same. I don't get it!
