Part number 1 in the illustration is the early production part that was only used on the first 6 or so vehicles....it did not fit well and was replaced whit a shorter version that worked really good. There was an exact reproduction out there but I forget who makes it. I will go in the basement and take a picture of the part.Does part #1 extend all the way to the back of the fender? Looks like it would be easy to replicate, I wonder why no one does it right, ie; exactly like OE?
The reason for the gap is the different distances between the fender and the inner fender between different vehicles ...that was the problem with the first design ( NO tolerance provisions) . The hole is for punting it in location with your hand during installation at the plant...it made it much easier to install. There is a gap but it still works really well.Yes, those are the ones I have, they don't quite reach the back of the fender. Also, what is the big hole used for?
