Used Cluster Gear for 1939 through 1948 Ford passenger cars and 1936 through 1952 Ford pick ups.

28 /24/18/14 Tooth, all helical, to use with 16 Tooth main drive.  Like Ford part number 51A-7113.

Uses rear thrust washer with four prongs and caged roller bearings.  Has small chip on two non-adjacent first gear teeth and on three second gear teeth; probably okay for use with 85/90 HP engines, not for use with a performance engine.
