I cant close the soft top on my rubicon.

I had this same issue the first few times I tried to latch my soft top. The trick is to stretch the top. Pick a nice hot day, leave the top "baking" in the sun for quite a few hours. The way I did it was to latch the front part of the top and pull the back corner pieces down hard and tuck the tabs into the body to lock them in place. The top will need to "bake" in the sun again for a bit. I wouldn't put it back down at night the first few times. As the night cools the top, it may go back to the original size and you'll be back where you started. I found that playing the "stretch" game on a hot weekend worked just fine. Of course, it's still a little tight, but if it wasn't, it would leak!!!

Good luck with your top!
