JKS discos....

I've just installed them on my 2000 Classic with an OME 2" lift, and am having a bit of a problem figuring out how to measure for the proper length adjustment.
I'm using a digital inclinometer to measure the angle of the swaybar,
but the swaybar has a compound curve to it, there is no flat surface to get a good reading.
How important is this angle, is close good enough?
Any ideas? TIA

Just kinda eyeball it. Close is good enough.

The stock configuration (ideal) has the ends of the swaybar pointing directly at the 3rd coil from the top.

Works great for me at 3"
