I pulled a full float 60 out of a 77' ford f-250 but can't id the axle.
Is it a 60, 60hd,or a 61? here are pics out the markings.
Also the markings read: c-37717, 336-76, and 81-2(could be 61-2)
axle pics (http://photos.yahoo.com/scottsbent70)

With the thick webbing it appears to be a Dana 70. all the 60hd I have seen have had 2 rows of webbing not the single thick one you have. They have also had the 60hd cast in above the pinion snout where your has the 7 cast in.

thanks for the reply
are there any lists where I can confirm what axle this is
