Can/should lower control arms be modified to accept sway bar?

Cameron, if money is an issue you can make your sway bar tabs for almost free with a scrap piece of 2x3 square tubing. Cut it at an angle and trim it to clear the flanges on the LCA. Kinda hard to describe but I can send you pics of mine if you like.

As redfish mentioned you can also weld bracing to the bottom of the LCA for next to nothing.
