LCA without Swaybar tab...

Yep, the aftermarket Addco swaybars come with a piece of angle iron with holes drilled in it that bolts through the shock hole.

A better option is to fab some up out of 2x3 box tubing and weld them to the LCA. I've done that several times before, it's cheap (free if you already have the tubing!) and strong. You don't even have to take the arms off the car.
