I used the 4 holes each side for the top + the 2 latches on the windshield. the tape stuff is like
this but its 1.25inches wide instead of .75.. basically the top when just set on my jeep was about .25 inch from touching by the door. but when bolted down it is now closer to 1/8 or less and the foam tape fills the gap nicely... and yes step 1 was removing all soft top hardware.
the uppers have nice thick weather striping all the way around 3 sides (windshield top and back side), and it seals and interfaces good with the hard top
. but the 4th side of the upper aka the bottom aka where the soft upper touches the hard half door, there is only a small round rubber seal of sorts that isn't secured by anything so it has no pressure for sealing. It could be a problem with our modified frames but still makes no since to me compared to how the soft top upper work..
I guess ill have to get some pics to make up for my lack of describing ability.
