I haven't decided yet. I have another set of the Nissan pickup bars that I could use. On the other hand, it would be much easier to use coil-overs. If I use the torsion bars I will likely mount them crossways on a fabricated crossmember above and behind the rear axle. My coupe has '82 Chevette springs in the rear and it rides comfortably, so conventional coils is another option. There are advantages and disadvantages to each system, so I simply haven't decided yet...
