Mustang 428 Cobra Jet Service Parts

Printer-friendly versionSend link via emailSave as PDF

People ask a lot of questions about service parts (such as spark plugs, air filters, oil filters, motor oil, etc.) for their Cobra Jet Mustangs. This page lists common service parts and their original Ford part numbers, along with modern equivalents if known.

Note that these parts might not be correct for Shelbys and other Ford vehicles equipped with a 428 CJ or SCJ. Please check your own part references to be sure! Note also that many of the part numbers listed here were found in the 1975 edition of the Ford Master Parts Catalog. The part numbers given are service part numbers, and thus do not necessarily represent the same parts installed at the factory during production.

In some cases I was unable to find a modern Ford part number, so instead I've provided an aftermarket part number. This part is probably not the only one available. Check other aftermarket vendors for their part numbers. Truth be told, you can probably find replacements for all of these parts at your local auto parts stores.

* There are some questions about the accuracy of several Master Parts Catalogs with respect to the rear brake shoes specified for 1968 and 1969. Both the 1970 and 1975 editions identify the 10" x 2 1/2" C6OZ-2001-A shoe as the replacement part, but observed evidence on multiple cars suggests that they were originally equipped with 10" x 2" shoes.

Please feel free to suggest additional items for these tables. I'm especially interested in documenting modern replacement parts for which I haven't been able to find Autolite or Motorcraft part numbers.
