Hey jtdean! I just picked up my ZR2 a couple weeks ago and ordered some RekGen flaps (Trophy sport for Silverado 2019+) upon seeing this thread. Just curious how you fastened the front flap most inner holes....I think they are referenced as "location C". There is no mounting screw on the truck at that location for attachment. Did you just leave those locations loose, or did you zip a screw into that lower cowl plastic piece? To backtrack a bit, I think you may have ordered the universal flaps....if so, how do the mounting holes in those work? Do you just drill holes in the flaps in the screw locations and then use the fender clamp? Any insight is appreciated!!!
Also, an FYI for this group, I also ordered RokBlokz for the 2019+ Silverado thinking they would probably work... They DO NOT!!! The front brackets they provide do not work for the ZR2, and the rear brackets they provide are wayyy incompatible. They are not returnable, so I guess I took one for the team.
