You could try the 66-67 type I think the hole is the same shape / size, as the fender in the photos below is a 74 up fender on my 67 (long story)
Here are photos of how my 67 work. (I was going on memory in my earlier post)

On a side note the small screw holes next to the square holes that the bezel retainers should go in graphically illustrates the difference between a 74 up fender and a 67 fender. (wish I had known that BEFORE The body work and paint)
