As James clarified, yeah the original d rubber liner is still attached and looks good from what I can see. You would just want the 5mm x 30 mm foam seal tape (runs about 10$).
Installation would be quick, it’s just a matter of lifting the topper from old jeep to new jeep and tightening it down.
Great condition, bought back in 2021, no leaks or issues to report. Selling the Jeep, so the top has to go. I only have the clamps for the bedliner.
In Nor Cal for the next 2 weeks or so before driving back to West Texas. May be able to meet somewhere on the way.
