Help With Front Fender Hardware Please

[Gold Rush]

I got my '74 SE Brougham back from the guys doing body work for me and quickly realized they had even less idea where the front fender mounting bolts and studs belong.  I have the factory body manual but it doesn't clearly show where the threaded studs go.  In the bag marked front fender hardware there were five studs (one was already installed at the top mounting location for a total of six studs)  and several bolts still not installed.  Here is the Flicker address for a photo.  I can't seem to figure out how to attach the photo directly.  https://flic.kr/p/2npEW8c

Hopefully someone can steer me in the correct direction.  Can't for the life of me see why two different length studs and also why so many.

Thanks so much for you help!!!

You can find pics of my 73 on my website. Anything you see, LMK I can either send bigger pics or take other specific ones for you.
