hey guys ive just bought a nearly rust free 89 yj! Ive had it about a week so far and already love it, but my question is how the hell do you remove the soft upper doors. Today it was 60 degrees outside, a perfect day to have some fun and i couldnt for the life of me figure out how to get the uppers off. i found one snap right behind the mirror and i thought they would just lift up but they wont budge! thanks!
