I beleive I installed the grille after the fenders but it was a challenge to get it in place. I am not sure that doing one fender after the grille would help very much.
I beleive similar to Kevin I installed the back bars to the uprights first, then installed the front bars but it does get pretty tight so I may have installed the lowest back bar, then it's front bar, then the second back bar, etc. I beleive the first time I had the bar sequence wrong and needed to take it apart to get the order correct. The bars are not all the same but the differences are not large enough to make the sequence obvious (at least to me).
