Installation Tips

This bracket assembly is designed to mount the common SI-style GM alternator in a centered location on 1946-1953 Flathead Ford V8s. The brackets are intended to be used with a narrow-belt, two-belt configuration.
To use this bracket on a wide belt car or truck you would need to cut approximately 1/2" to 5/8" from the wide boss on the base of the alternator. You would also need to cut a similar amount from the spacer supplied with the bracket. This must be done to get the alternator pulley to line up with the drive belt.
Bracket usually provides enough clearance for center mounting of an alternator even on Super Dual and Triple style Flathead intakes on late style engine. The alternator mounts in front of the bracket.
