Front Sway Bar 1965 Dart

Went to Addco website and the sway bar they have for 1963-1966 Dart looks just like the one installed on my Dart. Sent then an email about it and waiting for a response.
Their mounting instructions show a lip on the K member where the "L" bracket is supposed to be attached, but my K member doesn't have that lip. Any ideas on how to mount bracket?
