Hey Wrangler bob, is your TJ a 97?
You may benefit from fitting 04-06 model 'Softtop Bow Brackets'
MOPAR Soft Top Bow Bracket, Right - 55395006AD
MOPAR Soft Top Bow Bracket, Left - 55395007AD
I'm running a later model softtop on my 97 which fitted OK but not as tight as others I'd seen, so swapped the softtop bow brackets.
The later model brackets stick out a bit further and tighten everything up.
The top and windows are now as tight as a drum but recently I have noticed the rear sail panels starting to curl up at the 'J-channel'.
