Look at a Mazda pick up, same torsion bar suspension. Maybe Escalade?
<<Correction, they dont bag earlier torsion bar setups, only strut suspensions. what they do is lower the torsion bar to slam the front and then bag it to raise it up. Youll need to make a plate to mount the donuts between the LCA and something stationary. If you wanted to get crazy, you could float the rear torsion bar sockets and weld arms that extend out and bag the ends of those so you could alter the entire torsion bar rotation but they would end up under the seats? Good luck, probably would want to convert to an alterK8tion coil front suspension and bag those coils. >>
