So I'm sick and tired of hearing my sister in law complain about her "Crappy jeep" so I've taken on the task of sprucing it up a bit. In order to get a sticker her Yj needs a new windshield and in order to get a new windshield it needs a new windshield frame. When I remove the windshield frame will there be any surprises waiting for me in there? Any wiring/lines/anything in there? I had a look at the frames and they appear to be bolted on from the hinges/roll bar/and two brackets on both driver and passengers side, anywhere else?
