Up for Buy-It-Now is a new old stock  driving pinion grease seal assembly, Ford part number 7EQ-4676.  According to my Ford Truck Manual, this is used on the following models and years:

Timken Model E155
1948-1950 Ford Truck...F6
1951-1952 Ford Truck...F6

Timken Model H150
1948-1950 Ford Truck...Model F7
1951-1952 Ford Truck..F7
1953 Ford Truck..F, B700
1953 Ford Truck...F, B, C350
1954-1955 Ford Truck..F, B, C700
1954-1955 Ford Truck...F, B, C750

  I opened the package for the first time to inspect and take pictures.  The seal is in brand new, never used condition and is free of any dents or damage.  There are a few spots of extremely minor surface rust from many years of shelf storage.  May or may not need a light polishing up before installation.
