I could put a stock front back in fairly easily, I'd need a complete axle, steering including pitman, and I'd have to make a track bar, or get one of those RE ones with the 3/4 heim on the frame end. the rear end isn't anything special, well besides the ARB, Moser axles, and disk breaks, but if I were to use a waggy front end in the yj, I'd pull the axles and put the spicer ones back in, then toss them the long side inner for a spare,
it comes down to how much work is it worth to throw in stock axles, with 4.56 gears, then I'll have to buy either some 35" tires to fit stock wheels, or some 16" wheels to fit the stock bolt pattern.
on the scrambler thing, yj's are a dime a dozzen, scramblers are hard to find, and your going to pay for them when you do, IE: your 5000 tub and frame you mentioned, with a yj at 104, I'll have at least a 90* approach angle, and about that in departure angle, I still don't know if or how much of a fender I want to run, but I do want to be able to throw on a top and doors for cold weather, but still be able the throw the kids in the back, granted I'll have no cargo area cause the tank will fill that. I'm thinking about leafs in the rear, coilovers in the front, similar enough to the xj that it will probably handle the same, full hydro steering, so I'll have no steering issues other than spare hoses maybe. three link the front, but not to long of arms that I will loose ground clearance in the middle, and nothing hanging below the frame rails in the middle of the jeep. use 1/4" plate allong the sides of the tub, instead of sliders that hang down. ok, I've rambled enough.
