this is JMO, but you can't go wrong with the rears up front. 100 each for a 4 inch spring, and about 80 for the steering isn't much less than Marlin's hysteer 400. plus the steering box. that will solve all of your steering problems. the rear springs will move your axle foward. a good thing if you want bigger tires. I got around 5 inches with my setup. Built a 3 inch drop hanger. used 6 inch boomerang shackles. and added some wagoneer springs to the pack.
you can just bolt the rears in the stock location up front. but be sure to get some longer shackles. or the spring will hit the frame and limit the susp. travel. i think this will give around 2 maybee 3 inches of a lift. and don't forget about the front driveshaft. something must be done to it. or it WILL pull apart rather easily when flexed.
