The Dana forty 4 isn't any extra desirable than the corporate 10 bolt. So do no longer issue approximately that. the three/4 ton stuff off of any year ('seventy 3-87) will artwork. All 8 lug, so new wheels in spite of everything. you do no longer choose a 14FF, you need to use a 14SF, it is going to postpone no issue. do no longer overlook, the '88-ninety one Suburbans ought to be 3/4 ton as nicely, so extra ability donors for you. you are able to run the 14FF, besides the undeniable fact that it weighs a lot extra, and expenses extra in floor clearance. oftentimes besides the undeniable fact that, a D44 or 10 bolt/14FF mixture could be bought for truly little. 3.seventy 3 ought to be your bare minimum for gearing, 4.10 would be undemanding to locate, and artwork good with those length tires. you will destroy the rear 10 bolt for particular with that length tire, off-highway, and the small hub 10 bolt won't like them the two.
