Did you get the windshield brackets for teh doors? Those are teh hard ones to find. pretty easy to make but getting original ones are rare. They always seem to get lost. The later windshield lays back a bit farther than the early windshields. The early frames are wider so the top wont fit. the cowl openings between early and later CJ5 are the same. It raelly sint that huge of a problem with swap out frames. hinges are the same, just need the frame and glass. Wouldbe cheaper to do a new windshield frame that trying to find a later top, they are a bit scarcer than the early style and will cost more
