I have the mugen "style" hardtop I was wondering how do you install the window?

 

What is your rear window made of, plastic or glass? install the window frame seal on the glass first then seal it to the rear of the top. trial fit before installing to make sure it will fit right. use windshield sealant to install it once you check the fit. seal it good,around the edge of the window and the rubber frame or it will leak. take your time! i did mine. i have a cwing cf mugen replica top.
