The side windows on the CJ-7 World Cab I brought back from my years living in London were not factory windows, they were added sometime after. Here are a few more pics of it...
After I got it home, I tried it on the TJ I had at the time:
This earlier photo of that same top was published in Jeep World magazine, which was a UK publication (I have most issues of the magazine). It was painted maroon red by the person I bought it from, and when I bought it was still black on most of the inside. I just came across the original eBay listing, I had forgotten that I paid only 102 GPB, which was about $194 at the time. According to the seller, and also according to the editor of Jeep World, who I corresponded with at the time, they both only knew of one other CJ-7 World Cab in the UK.
It also came from the factory with troop seats in the rear, although all I got of them were the back cushions.
