Will a 2015 4 dr hardtop fit my 2007 4dr? Mine is a soft top. I'd like to convert it.

Why don't you just order the correct one for that year? I am not sure if it would or not, but possibly, If you want to do this if you can put the two side by side and look at any differences, form, fit, & function...

Someone is willing to give me one. They are not using it.

I figured as much, if you can't get a direct answer take some time and bring your jeep over to it and compare the two. Look at the body lines, and how it would seal on yours. If all looks good next would be to see how to attach it on your jeep. May want to take a tape measure...good luck.

Yes it will fit, but the screws that hold it on will not align perfectly in one of the holes. It is ok, as the remaining 6 screws will more than handle it. The problem you may run into is if your 2007 does not have the hook up to the rear wiper, defrost, and washer fluid. However, you will have this same problem regardless of which year jeep the roof came from. It is simply having it pre-wired for a hard top. You can purchase the lines from Jeep or a 3rd party and have them installed. Take the top, as even used ones run between $1,200-$2,000
