Well, one Problem, is the splines on the end of the inner axles is 28. solid hubs are 30, and IFS are 26, so hubs would certainly be a problem. Youre also dealing with a relatively small shaft, so breakage would be fairly likely. Why not use a taco rear end, FF it, but use IFS wheel hubs, and weld on the caliper brackets different (we could probably do this for you). Then youd have about a 63" wide rear. Wide enough?
