Is it (the header track) mounted to the inside of the windshield frame?
Our 97 had the same, ended up having to remove it and install the Bestop to the front (outside) track where the soft top installs.
I still haven't figured out what the inside header was for.
97 Sahara, 74 Renegade, 72 CJ5, 55 Willy's (the Beast) Boss 302, 6:34 gearing, Bose 901 speakers.
God I miss that Jeep. Forgot the kinda Jeep, 80 SX4.
