X2...I see you have the dash / windshield thing squared away. Its been some time since I had my convertibles back seat out but I think you need the seats out to install the rear side panels.
Thats cool about the back seat. It went in pretty easy.
I still have to paint the rear panels. I have the original white ones but after cleaning, its apparent that they need to be sprayed. Should they be white or off white???
Also, the wiring harness I have had lights going to each of those panels. Do they get lit on a convertible?
I don't see where????
I don't remember the wiring, but I drove mine for two years when I first bought it, and the lights worked back there...
