The Overlander CJ8 was for export only. Only 200 or so went to Alaska for the postal service in 84. All postals and most all Overlanders were RHD as far as I can tell but I have seen a few pictures of LHD Overlanders. I just like the looks of these tops much more then the inverted fiberglass bath tubs.
Oh and the rear barn door is way cool too. Much better then a lift gate and drop tailgate in my opinion. Comes apart in three sections too for easy storage. But eh side doors with the squired off corner are hard to come by. But I have seen people modify the top to include a filler piece to use CJ7 doors and that opens up allot of 1/2 door options.
