try this out. if you go up to the top of this page, you'll see a function button called SEARCH. i bet if you type in SAS, you'll pull up some really good info. what were your plans for the rig? before you start going crazy on the swap, you need to ask yourself if you really need the solid axle, or if you want to do it because it looks cool. try that search and those questions, and then come back and i'll give you all the info i can muster
edit: ***** the search function, it sucks. not to detract from broncozone.com, but go over to FULLSIZEBRONCO.COM and go to the forum. there is a dedicated SAS (solid axle swap) forum that you can read to your heart's content. i highly suggest searching SAS over there, and also reading all of the stickies at the top of the forum page. good luck
