I haven't REALLy looked at it yet... but was daydreamming here... What if you kept the 4wd box, go horizontally to the passenger side frame-rail, using a 90 degree (or whatever is needed) idler kind of arm, NOW Cross down to the factory axle location? Appropriate frame strengthening... etc.??? Would this not be easier (cheaper) than machining new flat top knuckles? Comments suggestions... please.
