I have on 06 unlimited and have seen gr8tops half cab and aev conversion but are there any other companies out there that make the same thing? I went to a 4wheel club meeting recently and talked with a guy with an old scrambler that has one and really love the setup!  

gr8tops is the only one i know of. you know that top has a bulkhead that mounts between it and the body tub......so you'd kinda have a unibody looking thig going there. you can get kinda the same thing with a soft top too. i know for sure that best top offers a half top and rear curtain that looks like they zipper together.  

Thats the reason I wanted to see if anyone else built one. The bulkhead is held in with adhesive tape. Theres gaps on the sides where the wiring harness for the hard top goes that they dont fill in. I asked gr8top about it and they said to use a piece of foam and make sure to have it rhino lined. If you rhino line it, its in for good so i dont understand why they wouldnt have something more like AEV's cab closeout, which is metal. Ive kept an eye on this guys build at  gprguy.com     He said he used a piece of foam like they suggested.
