The one that came on it when I bought it was a Sierra top and the windows were all fogged and couldn't see out of them. Decide to pay the extra money on the bestop so if any of the windows go bad or get damaged I can actually just buy replacements!
If you get them on ebay from EAG, and add 2 other parts you get 10% off. I added some grab handles and a neoprene fire extinguisher holder and got it all shipped for about $600. I was impressed at how heavy they actually are. The rear bumper you need to get about 12 longer bolts, because every bolt they supply to mount the bumper to the car and the spare tire holder to the rack are a good 1/2- 3/4" too short. Other than that you really can't beat it for the price.
