Accessory Brackets

Printer-friendly versionSend link via emailSave as PDF

This page contains application and service part or engineering (casting) number descriptions for the many accessory brackets used on 428 CJ and SCJ Mustangs. Much of the information listed here has been gleaned from master parts catalogs and ongoing discussions with people who work with these parts for a living.

Key to abbreviations: "a/c" = air conditioning, "ps" = power steering, "w/" = "with", "w/o" = "without".

Air Conditioning Brackets

Application and NotesService Part NumberEngineering Number
1968 Compressor MountingC7ZZ-2882-AC7SA-2882-A
1968 Pulley MountingC8AZ-2888-AC8AA-2A964-A
1969-1970 Compressor MountingC9AZ-2882-AC9AA-2882-A
1969 Pulley MountingC9AZ-2888-A
Replaced by D0AZ-2888-B
1970 Pulley MountingD0AZ-2888-BC9AA-2A964-B

Air conditioning bracket notes: These brackets are typically shared with other more common FE engines, like 390s. Engineering numbers can be found on the compressor mounting brackets, but they're not typically found on the pulley mounting bracket. The pulley mounting bracket is identified as an "Air Conditioning Compressor Brace" in the 1975 Master Parts Catalog.

Alternator Brackets

1968-1970 Mounting Bracket w/o smogC8AZ-10156-BC8AE-10156-B

1968-1970 Adjustment w/o smogC8AZ-10145-AC8AE-10145-A

Alternator bracket notes: Engineering numbers are typically stamped into the metal on these brackets. CJ Mustangs delivered in the United States were typically, if not always, equipped with a Thermactor emissions (smog) system, which included an air pump. The alternator mounts below the smog pump if the smog pump is present. The alternator mounts up high (in the smog pump location) if the smog pump isn't present. The cylindrical spacer should be pink anodized aluminum. These brackets are also typically shared with the more common 390 FE engines. The mounting bracket is also used to mount the smog pump (see below).

Horn Support Bracket

Application and NotesPart NumberEngineering Number
1969 SCJ Horn SupportC9ZZ-13826-AC9ZF-13826-A

Horn support bracket notes: With an external oil cooler (see below) used on SCJ engines, the driver's side horn was relocated to the passenger side of the radiator support, sharing space with the passenger-side horn. This bracket was used behind the radiator support to help mount the horns securely. Note that the 1975 Master Parts Catalog lists this part for use in 1969 only, but it has also been found on 1970 model year vehicles.

Oil Cooler Brackets

Application and NotesPart NumberEngineering Number
1969-1970 Upper MountingC9ZZ-6B633-AC9ZE-6B633-A
1969-1970 Lower MountingC9ZZ-6B634-AC9ZE-6B634-A

Oil cooler bracket notes: An external oil cooler was used with 428 SCJ engines, not CJ engines.

Power Steering Brackets

Application and NotesPart NumberEngineering Number
1968-1970 AdjustmentC7SZ-3A732-AC7AA-3C511-B
1968-1970 Mounting SupportC7SZ-3C511-AC7AA-3A732-B

Power steering bracket notes: While the majority of the brackets described here are made of stamped steel, the power steering pump mounting support bracket is made of cast aluminum. Note that a spacer is needed to mount the support bracket if a/c isn't present. If a/c is present the a/c pulley mounting bracket includes a mounting tab that takes the place of the spacer.

Smog Pump Brackets

Smog pump bracket notes: The bracket used to mount the smog pump is shared with the alternator (see above).
