I've only had two problems ever with removing the Bronco tops and leaks. Take care of how you store the top when it's off of the Bronco. Either set it on some old tires or wooden blocks to keep from damaging the seals. And be sure when replacing the top to not pinch the cab seal. The factory hardtop was designed to be removed and replaced without leaking, so a little TLC will keep you going leak-free for years. IF you have a headliner, be wary that it may start to peel from the back where the wind blows in while driving at hwy speed. I put a few screwws back in place after removing the top, then eventually fabbed a piece from the tailgate floor trim to hold the headliner in place with the top off for extended periods. You may find that once the top is off, you may never want to put it back on! My 84 Bronco has been without the hardtop for seven years, and the 78 for the last four. JSM84
