I have these numbers on my dana 60 rear end Build date 22 7B1 , BOM 602907 2. Can anyone tell me how to identify these? Thank You.

 

I did a few Google pages looking for a match to you Bill of Materials (BOM) code, which tells you the vehicle application and era, but found nothing in a 607xxx sequence. First I'd suggest confirming your number, then suggest Googling for that with the Dana name. There are a handful of sites dedicated to this, besides Dana's site proper. Stu

 

Thank You for the reply.

 

You are right, it is 602907 2. Thank You

 

A 602907 is a D60 from a '67 F100 1/2 ton HD. Semi floating. The gear ratio should be on a tag at the lower left of the cover. Stu
