I'm selling a CJ5 Hardtop on eBay and have had some people ask me if it would fit a 73 CJ5. As far as I know it will fit years 75 1/2 - 81. Could someone take a look at the pictures I have posted on eBay and tell me what years they think it would fit.
If the width of the top where it meets the windshield is the same as the width of your CJ7 windshield (the one in the pictures) it will fit '76-83. Pre-76 windshields are about 4" wider than '76-83 (which is the same as your CJ7).
