Hi all I'm new to the Porsche scene as I just purchased my first 911 about a month ago. I purchased an 1980 911 SC and I'm wanting to update the front and rear bumpers. Which factory take-off rear bumper covers will line up with the SC style rear flairs? Also will the newer style cover go over the existing rear bumper minus the guards or do I need a newer style bumper as well. Or would I be better off with an aftermarket fiberglass piece? Any info would be greatly appreciated as I am out here in the great wastelands of Kansas and about the only guy with 911 in about a 100 mile radius I think.
