Several different air cleaner assemblies were used on Cobra Jet Mustangs during the 1968, 1969, and 1970 model years. Instead of trying to identify them all on one page, we're going to separate them into several broad categories based on air cleaner type and model year. Use the links below to jump to the ID pages.
Ford power steering pumps are identified by basic part number 3A674. The pump used on Cobra Jet Mustangs is known as a "Ford-Thompson" power steering pump because it was manufactured by two companies, Ford Motor Company and TRW (which was known as Thompson Ramo Wooldridge prior to 1965). It's a belt-driven slipper-type pump that includes an integral steel fluid reservoir. The reservoir is attached to the rear of the pump and the pump body is inside the reservoir.
Ford identified the steel engine oil cooler used on 428 SCJ engines using basic part number 6A642. The 1975 Master Parts Catalog identifies the pump using service part number C9OZ-6A642-A. The engineering number is C9OE-6A642-B. The same cooler was used on the 1969 and 1970 Boss 429, 1970 429 SCJ, and 1970 Boss 302.
Ford alternators are identified by engineering part number 10300. 1968, 1969, and 1970 Mustangs were originally equipped with either a 38A (amp), 42A, or 55A Autolite alternator depending on the engine and installed options. Certain power-hungry options, like air conditioning, typically included a higher output alternator as part of the package.
Ford water pumps are identified using basic part number 8501. Like most water pumps of the time, the pump used on 428 CJ and SCJ engines is driven using a belt and pulley arrangement. The pulley bolts to a flange on the front of the pump. The belt routes around the crankshaft pulley, turning the pump with each rotation of the crank.
Ford rocker arm (valve) covers are identified using basic part number 6582. Ford used three basic valve covers on Cobra Jet Mustangs during the course of production. The April 1969 Master Parts Catalog was used to determine the original 1968 and 1969 service parts numbers described below.
FE engines require a spacer plate between the rear of the engine block and the transmission bellhousing. The picture below shows the plate used for both automatic and manual transmission applications starting with the 1968 model year. Notice the three small holes at top and the large hole at bottom. The rear of this plate is stamped with a date and shift code of "11 28 D3". The large hole to the left in the front view is for the starter.
The timing pointers used on 428 CJ and SCJ engines are identified using basic part number 6023. The pointer is made of stamped steel, and is bolted and screwed to the front of the timing cover. This part was painted on the engine after installation, so it should normally be painted Ford Dark Corporate Blue. The pointer is attached to the timing cover using a sheet metal screw, and is secured further using a bolt that mounts both pointer and cover to the front of the block.
The front cover used on 428 CJ, SCJ, and other FE engines of the period is identified by basic part number 6059. The cover is made of cast aluminum, and is bolted to the front of the cylinder block to protect the timing chain, timing gears, cam eccentric (used to drive the fuel pump), and crankshaft snout. This part was painted on the engine after installation, so the outside should normally be painted Ford Dark Corporate Blue.
The thermostat housing (also called a water outlet connection in the master parts catalogs) used on 428 Cobra Jet engines is a cast aluminum piece that was also used on other FE engines of the same vintage. The 1975 Master Parts Catalog identifies the housing using service part number C4TZ-8592-C. An engineering number of C8AE-8594-B is cast into the top of the housing.
