Ok I agree with the opinions against the OEM bra or bras like that in general. I did purchase it to bridge me to the point where I decided which invisible product to have applied. I recently had the
XPel ultimate film applied and am very happy. Back to the bra. While it can back a little challenging to figure out how those darn tabs fit in those creases I got to a method that worked fine and frankly once installed the bra was a tight good looking fit. What you need to do is look for the place around the headlight which is not as tight and the tab goes in then use that same relative area and insert the other tabs in that side by sliding the tabs one by one to the final position until you have all three tabs on the top in. Do the same for the three tabs that are below the light and your done then move to the other side. Don't snap the part of the bra that goes in on each side of the engine compartment area until both headlight areas are fully set.
Hope this made sense. Good luck. Here is a pic of my Vette with GM bra before I had XPel installed.
