If you find it PM me . I can see what Monty is saying about the pivot on the Cal-Tracs and the IC not changing. But, how does the IC change on a four link? The bars are only moving up and down, the mounting point is not moving, it's welded in the car. It all seems to be theory to me. The Cal-Tracs have a single mounting point but so does the four link, the spring eye for the Cal-Trac and the front bracket on the four link.
I'm probably way out in left field on this and by no means an expert. Oh, I have Cal-Tracs on my pig .
This the kind of thread I like to read, hopefully I can learn something .
The 4 link, with lots of adjustment holes, can have 1,000 possible ICs with all the different holes on the housing and chassis brackets. The IC is where the two bars would cross, if you extended them. So the IC is projected, not physically mounted. A leaf spring, or ladder bar, the IC is where it is mounted to the chassis, period, it can be nowhere else. Now multiple mounting holes, can move the IC up or down, but the length is common, because it is a one piece, fixed bar, attached to the chassis. So a 32" ladder bar, has a "32 out" IC center. As said the height can vary with mounting holes, but the length will ALWAYS be 32". The IC of a leaf spring, is out as far, as the front segment is long. As far as the front mounting point of a CalTrac, lower bar, altering the IC, it can't, because the pivot point on the chassis never changes. All that adjustment does, is change the amount of leverage, that the spring, applies to the chassis. Just take some time and actually look at your CalTrac bars, visualize what happens as the rear tries to seperate from the car and the pinion rolls up. You will more understand how the adjustments change the way the force is applied to the spring pocket.
