LCA sway bar tabs ?

researching info on sway bars, well ahead of a purchase, need one item understood,, on the lower control arms,, some have "tabs" for sway bars, some aparently do not,, guessing the tabs are where the sway bar struts mount,,
if I get a set of LCA's with out the tabs,,,
* guessing I can buy or fab tabs?
** is it difficult to propertly weld the tabs in the correct location? basically is a template or mounting dimensions available?
*** if a template is not available how do you decide where to stick the tabs
**** I want to learn to weld, and have the equipment, but don't yet, so will it be best to get the Lower Control Arms with the tabs?

thanks
