My phone won't pull up the full pics right now, but the thumbnails look like a CJ6. made from 56(?) -75, they were basically the same as their CJ5 counterpart of the same year but with a 20" longer wheelbase.
IMO it doesn't look like an original body. Its too smooth. And not sure if the '6 should have the gas tank under the seat, but I don't see a filler neck for it. Front fenders look odd also.
Post some pictures of the grill and interior and maybe someone can give you more info
