Locating sway-bar tabs

I am rebuilding my front suspension and doing some improvements along the way. I am going to poly bushings and I am going to weld in the stiffener plates from PST. I also am adding an anti-sway bar which means I need to weld the tabs onto the lower control arms where the links will be attached.

The instructions from Hotchkis only show a picture of the suspension all put together with a note that says to locate these tabs to provide 1/8" clearance from the strut rod. I don't want to put the whole suspension back together and then weld these tabs in place. I'd like to know where to locate them on the LCA when its disassembled.

I've contacted Hotchkis tech support and they told me they'd get with their engineers to get location information. No dice so far an it's been a few weeks. Not too impressive.

Anyone have some measurements from features on the LCA or maybe a template diagram that would help me weld these tabs in the right location?
