The 911 Slant Noses

When the now-famous Porsche 935 came out back in the 1970's, it sported a new front design which eliminated the 911's round headlights, thus forming a totally flat hood, or "slant nose" (or slope nose). Now aftermarket companies quickly got a hold of this design, and began converting regular 911s to the slant-nose form. It wasn't until the mid 1980's when the Porsche factory began offering the Slant Nose body option to the 911 Carrera or 930 Turbo. You could get just about every combination--the Carrera Slant Nose, in Coupe, Targa, or Cabroilet form, or the 930S, meaning Turbo Slant Nose, which came in all three body forms as well.

Many times, it is very hard to tell the difference between an original factory Slant, and an aftermarket conversion. Here are a few guidelines to go by when diagnosing the 911:


1) 4 studs at the four corners on the underside of the louvers
2) Splash guards attached to the 4 studs
3) Imperfect headlight door jambs
4) Japanese headlight motors
5) Wiring to lighting
6) Welded light buckets that intrude onto the wheel hose skirts
7) Evident mig-welding of 3 seperate insert panels to factory fender
8) Windsheild washer resevoir in left fender changed(or cut down)
9) Dents in the battery area of the shirt to fit under buckets
10) Cut out of the bumper shock support to fit buckets
11) Composite or plastic rear vent slats
12) No octane sticker on back of fabricated gas lid door


1) Wood rear vent slats
2) Dual oil cooler in rear qtr vents with screens
3) Jack extentions extended factory welded to rockers
4) Factory stamped part number on rocker panels
5) Two piece rear vent hole
6) Exact die cuts in the corners of louvers

Hopefully with this info you can determine if the 911 in question is in fact a factory Slant Nose or not.
