you are correct in that there are two euro bumpers available.
here's some pics that show the differences in the lower profile when mounted on a 81 SC.
the part numbers are available if you do a search on 'euro' bumper guards, I imagine.
either one will work, just that if anyone gets down on all fours to check your gap, they can see wheither you are using the 930 pn or the 911 pn. Bill K
