[VAC] Rock Guard for '77 Sovereign?

["David W. Lowrey" <dave_lowrey@xxxxxxxxx>]

I have a '77 Sovereign.

Were rock guards for the front window a "standard" item? I dont see them 
mentioned in the owner's manual. However, there are "male" snaps around the 
two curved sides of the window.

Any idea where I can get a rock guard?
