It's the smaller diameter like the CJ7. The build date on this one is 1/84. Jeep stamp is very deep on the sides meaning not even close to a JOOP. From what I can tell the early 84 had the taillights like mine and the smaller diameter rollbars and a slightly different decal package. I've gathered this from looking at photos of other Overlanders but I dont know when they were built. Late 83, early 84 is why I have slate blue interior, I think. Except for brochure photo I haven't seen another with slate blue. Mostly nutmeg, 1 garnet, 2 nutmeg Laredos and of course 1 blue. Rear rollbar feet do not have little flip up tiedowns. Rollbar doesn't bother me or I woud pull the rollbar from the postal. Wait, remove both tops, rollbars, reinstall rollbars, reinstall tops. It really doesn't bother me...
