The biggest difference between The CJ and YJ tops is that the lip that comes down over the tail gate is on the inside on a YJ and on the outside on a CJ. Other than that they will interchange.
That's the issue with this top. The rear is one piece of glass the cj top has a rear hatch frame surrounding the glass that is the one I want. This top was on the jeep when I got it but I would like to have the original top. Thanks for posting.
