ok, so its been awhile since an update but i finally have the rotors done. I created a drawing to show the dimensions that i used to open up the rotors so feel free to use them. The 8 through holes are opened up to clear a 1/2-13 bolt. The originator of this conversion decided to helicoil the existing threaded holes and run 7/16" cap screws. Since i had access to a lathe and many 1/2 cap screws i just figured i would turn down the caps to 7/16" dimensions. After checking clearances, i feel comfortable running them. Also i ran my numbers in Billavista's brake calculator and my system comes up short of what it recommends for my rig; however, i ran the same calculator for what my dana 60 and 14 bolt use to have and it came out less that this new set up so it should be ok. I do plan on throwing a pinion brake up front as well with a prop valve to help cure any uncertainties i may have ( i know this brake will be worthless when it comes to actually being engaged in 4wd, but this is more of a precautionary for driving to any trail than anything). Anyways, here are some pics of the my renderings, finished rotors, and turned down socket cap screws.
The rotors are for a Front application of a 2003 Lincoln Aviator.

Also i have completely finished the lower link mounts and now i'm going to take the knuckles off and start to remove the diff pan and start to construct a skid. I'm also looking at flipping the knuckles and running a double ended cylinder on the front (i have talked with PSC about the concern with ackerman angle and they believe that the deflection in the 49's on 17's would be enough to counter out proper ackerman angle anyway so i'm going to run with that idea). Anyways, not much on pictures for those but heres some.
