I have a 78 dana 44 hd out of an f250. It has 4.10 gears. The axle in my truck is a 78 dana 44 from an f150. I am doing an 8 lug conversion and my new sterling has 4.10 gears. The gears in the dana 44 f150 axle are 3.50. Are the gears/carier/ etc the same between the two. Also what master overhaul kits to you guys recommend. I need all new wheel bearings, axle seals etc..
