So I order a Trektop NX from 4WD for my LJ and to my amazement, I receive the new top in two days. I install the new top and it seems to be going great. Not too hard to fit and looks good. Down to the last zipper when it happens. The back window pulls apart where the zipper is stiched into the clear window. I call and speak to 4WD service and they stated it will be a warranty and tell me the new window will ship in seven to ten days. This was on friday, so today, Monday, I decide to call back and see if they might have a better time frame because I leave this coming friday for vacation. I call to see if they have a better ship date and hear that the window is shipping from Bestop in two to four weeks! I ask if there is anyway of getting it sooner and hear that Bestop dosen't stock the windows and will have to make the replacement. Well, I have ordered from 4WD a few times, and always had luck with them and fast service. But I think I ordered my last part. Nothing like spending your hard earned money and getting shafted. Wish the rep I talk to would have told me the two to four weeks to start with. I would have kept the old top to at least keep the rain out.
