2000 Impala rear wheel arch design

I recently inherited a nice 2000 Impala. Very pleased overall. But I noticed that there is a ledge / pocket at the front edge of the rear wheel arch that catches debris flung off the wheel. I figure this
will rust out in no time here in Canada. Why did GM design it that way? I noticed that the design was changed in later models. If I cut a hole, I will leave an exposed metal edge which will rust for sure. Comments?

There are alot of model that have the rock catcher in front of the rear wheels. Fords Maquis & Crown Victoria in 2001 eliminated the lip around the rear wheelwell openings.
Check with a Chevy parts department, I think in 2001 the rear wheel wells had a plastic liner that fit right up gainst the the area in question. You may be able to add it to your 2000
