Make your own template.

To make the template I would use the snorkel and trace its outline on thin cardboard.

Cutout the big hole first and then put the cardboard on the snorkel and trace its outline, remove and cut the template out.
Put the template back on the snorkel, tape it down so it will not move, using an awl or nail, locate and punch the centers for the small holes.

Using the template, locate the correct angle on the windshield pillar and transfer the hole to the fender. If you have the old fender it can assist you in your efforts.

I may have over explain, but it may help some. Let us know the results.
