The fronts should be curved from bace up and back. Parallelogram with curved leading and trailing edges. Not like the side VGs.(trapezoid)
This is a poor example with witch to condemn all VGs. Poor fit and finish .In my opinion.
They did have to make thier own on the fly but that was because none of the actual makers of the vortex generators for sale at the time wanted to supply their product to be tested in an actual wind tunnel on an actual truck. That sort of raises a red flag to me but it was back in 2006.
