well, it depends on the weight of the engine trans assy and the size of the t-bars, and your personal preference for stance. Generally, I think if you turn the torsion bar adjusting bolts so that the heads of the adjusting bolts are somewhere between flush with the bottom of the LCA's and proud by the height of the head of the bolt of the bottom of the LCA. it should be fairly close. Of course, don't final tighten the pivot pin nuts, until you've got it resting on all fours with everything installed and a 1/2 tank of fuel. Some people even include the driver sitting in the driver's seat.
