Strut rods

I am doing front suspension bushings in my 72 Demon and found front of strut rod has a grove worn in it from rubbing on K frame. Was thinking of migging and grinding for repair. Has anyone tried this before or would it weaken it.
Thanks Jeff
I WOULDN`T BE AFRAID OF BUILDING IT UP, IF IT ISN`T TERRIBLY WORN, it`s only supposed to be a straight line load/pull for the most part.
