Honestly. You'll be better off buying a top. I've been looking for 2 years. Most windows will have a hole or need zipper repair. There are several used tops on ksl.com in a variety of conditions.
I have a full set of side and rear windows for a Rugged bowless top. Brand new, never been used for an LJ. They didn't fit on my Poison Spyder cage I put in it. Comes with the protective case for them also. $100
