I have never seen a late model with a solid axle, but it could be done the same way as Rick's. It would, however, need the IFS mounting stuff torched and ground smooth, the steering would need to be completely fabricated, coil buckets would need to be made, and then you have your coils, track bars, axle, and all the labor for this swap. The labor would be close to the same as what would be required for an early model explorer. There are no kits to my knowledge, but I am sure there isn't one, nor will they make one, since all the stuff needs to be torched and gorund smooth, and all the other parts needed, and there probably isn't enough demand for a kit like this to be made.
