Ford 351M - 400 Alternator Bracket (400M)
Ford 351M and 400 Alternator Brackets are special and you cannot use the more common 351W bracket or even a 351 Cleveland Bracket. The 400 (or 400M as it is sometimes called) brackets are hard to find these days. This bracket is designed for use with either OEM or CVF Racing pulleys. Mounts alternator on the passenger side (USA passenger side).
