When I got my Jeep it had a really beat up soft top, I recently got quadratecs quadratop and used the hardware that was on my factory top and I love that I replaced the whole thing. The color was faded after 14 years and the new top's color really pops and looks great. I had a problem with the zippers as well and didnt want the risk of it being the inner zipper and wasting the money on a window. The top was 310 with tinted windows 300 w/o. It took maybe 10-20 minutes for me to install it.
