Hey Nifty, where are the notches on the grille bars? Is it one notch for the top one, two notches for the second one down and so on? I had mine rechromed and I have heard about these notches but dont see any. I took pics of it as I was taking it apart so I could stumble thru that way but if I could find these notches life would be a lot easier. Thanks in advance. Mine was bolted together and not riveted. I bought the bolt kit from Chevy Duty. Weeds
