Hi . I would be careful . If I am not mistaken , the 75 and earlier didnt have a boxed in frame ( someone correct me if I`m wrong, please) . I bought my 79 CJ5 for 2 grand CANADIAN , which is about $ 1300.00 US . Everything was great except the tub was junk ( Can you say RUST !!). I would try and find one 78 and up .
My .02 worth
