rear suspension upgrade ?

It really isn't that hard. measure the angle of your spring plate before you disconnect it and when you have released it from the trailing arm. I think if you get it real close you will be close to the ride height you had before. On pelican you can find a ride height calculator that uses weight of car torsion bar size and angle of spring plate. I think the spring plate gives you about a three quarters of an inch of ride height adjustment with out re-indexing the the torsion bars.
