Wow, $81 and climbing!
Based on what Walck's told me and from what I've seen, the originals did not have the fender strap welded to the hold-down frame. The fender strap fastened to the J-bolt on one end and then of course the fender stud on the other......and that makes sense to me as not all batteries and not all jeeps would have been identical so a little play or adjustment in the strap might have been needed....
But, who really knows? There could easily have been more than one type hold-down that Willys used over the years....
