This is a new very high quality and very correct data plate backing plate. This is the master plate that all the small data plates attach to. These are bad about rusting out. This is a new very correct US Made reproduction. It is laser cut and not some junk a guy in the garage with a drill made. This is 10 7/8″ X 7 1/4″. It is 1/16 thick just like the originals. This will fit the M38, M38A1, and M170. QTM Parts
