Factory soft top frame....I had an 01 TJ, i now have a 91 YJ. I felt slightly retarded trying to get the top off. Heres the jist for it.
Step 1) Forget everything you know about a TJ.
Step 2) The soft upper door halves are buttoned on along the bottom.
(You have no idea how long it took me to discover there are buttons everywhere on a YJ top.)
Step 3) untuck the top from the lip above the windshield.
Step 4) Take off all the windows (can do this from here or earlier, I just forgot to write this step)
Step 5) unbutton the top from the door frames
Step 6) Roll the Top back.
This literally took me 4-5 hours to figure out. Keep in mind, I was also replacing the top, but none the less, it made me feel Fn stupid.
