We have a 1973 Mustang convertible we show in the unrestored class with the Mustang Club of America (MCA). We need to know what the assembly line battery looked like. We know it was a Motorcraft, but have no reference as to what it should look like? Currently we have a reproduction Autolite. Kansas City, Missouri
The correct Motorcraft battery for your 1973 Mustang is a blackcase Motorcraft with red letters and red Motorcraft caps. This battery was used in 1972 and 1973 only. Late 1972 was the beginning of the newgeneration Motorcraft batteries with the lightweight clear case, first used as a replacement parts and service battery. By 1974, the new version was the OEM battery. An OEM black-case Motorcraft is a rare find due to the limited two-year use as an OEM battery.
I have an opportunity to buy a pair of D0OZ-1130-A disc brake rotors: N.O.S. in Ford boxes. Is this the correct brake rotor for a 1971 Boss 351? These rotors are mint in their boxes! They are pricey though, so I want to be certain they are correct for my Mustang. Bill Jones Nashville, Tennessee
The D0OZ-1130-A disc brake rotor is correct for all 1970-1973 Mustangs with disc brakes. Make sure they are the original production-style two-piece version, as Ford made some one-piece service parts units in the late 1990s.
