Decal location
CJ Decal
SCJ Decal
5. Valve Cover Emissions Decal
The Valve Cover Emissions decal was placed on outer edge (towards front) of driver
side valve cover.
6. Air Cleaner Element Service Refill Decal
This decal goes on outer edge of air cleaner at about 4:00 as viewed from the front.
7. Snorkel Part Number
The part number for the snorkel (D0GF-9D626-A) is stamped in white acrylic paint on
the underside as shown. The photo at right shows a closeup with a scale in case you

Mustang C Code – Decal
Cougar J Code – Decal
8. Air Cleaner Engine Displacement Decal
- The 71 429 Mustang J Code (Ram Air) engine air cleaner did not come with a decal.
- The best we can tell, the 71 429 Mustang C code (non-Ram Air) air cleaner did as shown.
- The 71 429 Cougar J Code did come with a decal as shown.
- The 71 429 Cougar C Code probably came with the same decal as the 71 Mustang C code, but we have
not got confirmation on this yet.

How to Identify Coating/Platings on Underhood Parts
Click this link to go to the page on Coating/Plating Identification: Identifying Coatings and Platings
Identifying the different types of coatings used on components can be a tricky job, especially since both Zinc and Cadmium plating were used in 1971. An engineer from the Ford Fastener Engineering Laboratory has provided some “Rules of Thumb” to use in identifying coatings and platings. These have been captured in the table below along with some photos of these different coatings.
