that would be a lot of work. to go back to stock, you'd have to remove the 4link, weld the rear spring hangers back in, remove the front bag mounts, put the torsion bars back in...and probably quite a bit more.

It would be relatively simple, however, to put coil overs on all 4 corners...they just bolt in where the bags are now in the rear, and would only take a little work up front. That way, you'd still get adjustable suspension, and the traction benefits of the 4 link.
