Anyone know the length of the stock arms? I need to measure my Tomken's to see if they are actually longer. I've got 5" of lift and the arms are acting funny, like they arn't the right length or the right angle.

By strange coincidence, I was just looking at a chart of control arm lengths from the old 
forums, posted by the artist formerly known as Alyn:
LCA = 15.75
UCA = 15.00

Can you eail that chart to me. [email protected] I forgot about the old post I had from Alan. I see to have lost the chart diagram that went with it.
"For the upper arm:
15^2 - 1.5^2 = (corrected UCA length)^2 = 14.925
14.925^2 + (lift - 1.5)^2 = (new UCA length)^2
the example 4" lift yields 15.133 or approx 15 1/8"
For the lower arm:
15.75^2 - .75^2 = (corrected LCA length)^2 = 15.732
15.732^2 + (lift + .75)^2 = (new LCA length)^2
the example 4" lift yields 16.434 or approx 16 7/16" ?"
