I will be converting my 99 super duty dana 60 front to an 8x165 lug pattern with a custom-built hub on my 1 ton Lj. What I am trying to find out is what brake rotors I can use that will match the dimensions of the stock ones but will keep the new bolt pattern.

As far as my research goes, the stock rotor dimensions are:

38mm Rotor Thickness
99.5mm total width

The aftermarket one that I am looking at has the dimensions of:
35.5mm Rotor Thickness
101.9 total width.

Will this aftermarket one fit and clear the hubs, calipers etc. so I can use it with my custom front hubs?

I am unsure how the small differences in thickness will affect fitment and such.

-Thanks
 
I have also considered keeping my current rotor and redrilling holes to match the 8x6.5 pattern. From everything I read, I should be able to get away with it since my rotor is sandwiched between the wheel and hub. I am interested in hearing your opinion on it @mrblaine

We redrill all the time including 6 on 5.5 over a 5 on 5.5 which cuts through part of an original hole with no issues.
