Full disclosure: This is my method. May not work for you.
So after searching a bit and not finding exceptional resources I went ahead and said, "f*** it" slammed a beer and started taping.
I started by using the assembled snorkel as a base template. I marked potential drill points in pencil.
At this point I had to decide, from which direction I would work. I decided to work from top to bottom. I drilled the first hole and prepped with por15. I decided on M8 nutserts and used a 27/64" drill bit (you could use a slightly larger bit for an M8 nutsert, but for me this was ideal because it required slight pressure to fully insert the nutsert prior to crimping it).
As you can see the nutsert is placed just before the curve towards the windshield (measures provided below). I then bolted the bracket to this nutsert and re measured my initial marking. I did not get any bit walk when drilling the first hole. Even still I decided to keep the bracket in place to prevent bit walk on the second hole. As you can see below, work well for me.
Also that is the moon, so its time for sleep. A few days of rain and family business prevented me from pressing. I did have to reapply tape and decided to remake tentative marks. I bolted the snorkel in place with the a-pillar braket, did my mark ups and pressed. Again I installed the upper sections nutsert, secured it. Validated the lower sections marking (still no bit walk). For the upper and lower section bolts I could not use the in-place snorkel as a guide like I did with the a-pillar braket using my chosen bit size. you could use a smaller one and step it up for finishing but I fear tearing the sheet metal.
