Fox 2.5 assembly and spring installation questions

In light of the corrosion on the threaded portion of my existing 2.5’s shock shafts I decided to buy replacement fronts and install my Geiser springs on them. I have a few questions prior to assembly.

I figured that I would be a good idea to remove the set screw on the collars and put some never seize on it. Is there anything else I should do? Put wax/sealant on the exposed portions of the shock?

I also purchased new shock “hats” and upper spring isolators. Does anyone have a method/alignment tip for clocking the three studs of the hat with the the lower shock bolt? I have photos of the one I removed but I wasn’t sure if “eyeballing” them would be accurate enough and I’d rather avoid trial and error. I figured worst case scenario when I get the old one out again I can compare them with the new ones, but if I could have it done prior it would save some time.

Thanks in advance.

Just found this for my second question. I assume the gen 2 is similar to gen 1 in regards to the one stud in line with the hole in the bottom.

Last question.

What is the bottom of two reductions in diameter for? The top one bottoms out the shock hat. Am I missing a spacer?

thanks.

I can't find anything in my pictures and don't remember, does anyone know if the spacer is part of the rubber bump stop:

I am starting to think the shaft is machined in that area for clearance since the shock hat has a rubber bushing in the top and may allow some movement.

please see below for photos of all the items I have to install (hat, upper spring isolator, and bump stop)

No bushing on mine there...

Good deal! Thanks for looking into it
