By reading /searching here I believe I have it figured out. Do I? My situation is based on a M1008 Dana 60 Front, matching 14FF rear and a set of 12 bolt Humvee wheels. For the front: I can buy a 1 ton 4WD Front Disc Brake Rotor for a DRW Pick Up truck and the fronts wheels and tires (assume tire size is not an issue) will work with this simple mod. Duralast Part Number 5564 or equivilent For the rear: I need to convert the drums to Disc - using a kit like: http://www.offroaddesign.com/catalog/14FFdisckit.htm and then add two inch spacers like: http://www.offroadoverstock.com/store.cfm?Product_ID=8on6.5&page=details.cfm&cartaction=none&thisrow=2&action=list&criteria=156&startrow=1&mystartrow=1&maxrows=10&cat=32&man=&stay=&afid=&searchcat_id=&itemprice=&searchfield=&searchman_id=&boolean=OR&var1=&var2=&var3=&return_product_id=&makeid=&modelid=&modelyear= Is it just this simple? Thanks for the help, I pick my wheels / tires up tomorrow.
