Update.

Wolf was out running around in the back yard through the snow, and after about 15 minutes I brought her back to the garage. On two sets of suspension the torsion bars with the enlarged pads had still managed to slip off the swing arms causing a real serious sag in the front end.

I am going to replace the pads with plastistrut I beam. The I beam sized to fit over the swing arm. Hopefully this will work. Actually as I am writing this I think Brass C channnel would be even better. I'll keep you posted.
