I have actually does this mod to a Camaro inner fender by using my old Firebird inner fender as a template.
There is a larger "notch" that has to be cut at the front inside edge to clear the Firebird's large "boomarang" bumper support where it bolts to the subframe. That mod does not alter how the inner fender mounts to either the front fender or the rest of the front clip structure.
In other words - you won't find you have a problem until you try and mount your front bumper assembly if you are using an unmodified Camaro inner fender.
