PML makes two covers for the Ford 7.5 inch (7½") ring gear differential. PML Part Number 7043 has a straight fin design and a round shape.

Applications:

This rear end differential cover fits the Ford 7.5 ring gear. Some possible applications are:

• Bronco II, 1984 to 1990
• Ranger, 1983 to 2012 (the 4.0L engine Rangers usually have the larger 8.8 inch rear)
• Mustang, 1982 to 1986
• Aerostar, 1986 to 1997 and minivans
• Mazda B2300, 1994 and newer

Always check your truck to verify differential and look for clearance. Configurations vary. This cover is larger than stock so make sure you have space for a larger cover.

This cover may also fit some minivans, Crown Vics, Grand Marquis cars, and Thunderbirds. The Ford 7.5 stock cover is about 9.75 inches vertically. Some models may have the larger Ford 8.8 differential (PML part numbers 7064 and 9519), which is more rectangular in shape and longer (vertically). Please check carefully which differential your vehicle has and if you have clearance.
