[farmallmta]

Can anybody tell me what the spline count is on the axles of a '69 F-250 Dana 60 rear end? Thanks!

Your 1969 F250 Dana 60 (if original) is 16 spline... I broke plenty of axleshafts myself...

From my experience, the F250 dana 60 stayed 16 spline through at least 1973. By 1977 it had 30 spline axles. Switch therefore must be somewhere inbetween.

You can tell with 100% certainty by looking up the BOM number. PM me if you need help.
