Funny my 73 does have it & the hole in the fender (probly a 72 fender or the previous owner(s) added it The 74 has none & no hole
But then again, I welded up all the body side moulding holes on the 73, so I guess you never know!
Funny (well not really) story bout holes, Ron(old body guy) was helpin me do the patches on the front frame rail, there was one bracket bolt hole near the work I had blue marker on it so we could see it & not to weld it, well Ron started doing the spot welds & continued right on to that hole, so it's now solid metal!
