The 71 install kit came with all the screws for the bezels and like 8 screws with small flanges on them. it also came with 8 square plastic pieces which you screw the screws into. They have small metal retaining clips at the top. Look at the brackets on the bottomwhich the grille sits on. they have a cut slot in them.. from narrow to wide so these plastic pieces slide into.
Also underneath the header panel.. there are, i believe three of these slotted areas for these clips. My question is why do I have 8?? I do not see all the spots they go into. I guess I'm not sure where all the grill flanges bolt screw up. Mine was disa ssembled before and they put 1/2 of the wrong screws and these plastic pieces werre missing.
