Looking at buying a D60 from a 60s F100. I was under the impression is was a D60 center with 9" outers. The diff is centered and 5x5.5. Perfect since it was ~60.5" WMS and I could swap out to 1.5" 35 spline shafts. Run 8.8 disc brakes. I do not want a 9" center. Plan is to narrow a 99-04 SD60 to 29.5 spring perch width or 61" WMS. Convert to 6x5.5
The ring gear was dated 10-1-65.
I came across this thread saying:
1/2 ton Dana 60 - Ford Truck Enthusiasts Forums
Optional for F100's: Dana 60.2 = 1963/66 F100 / Dana 60.3 = 1966/69 F100. Both have Limited Slip, but neither is a Dana 60 as they were only installed in F250's.
Dana 60.3 available ratios: 3.54-1 & 4.10-1. 1966/67's use different axle shafts than 1968/69's, but both have 30 spline axleshafts.
The only 1968/72 F100's that came with 31 spline axleshafts: Optional 9" H/D with a 9 3/8" ring gear & 4 pinion Traction-Lok.
ring & pinion....same
clutch pack kit....same.
Note,the 60.3 lists a gasket,axle bearing,bearing retainer,and seal like a 9". The 60.2 does not.
Then Dutchman website order form (below) lists the S7 bearing which is mopar 8 3/4" from what i can tell. Can't imagine why that would be spec for a ford.
Also below is the actual bearing end. Which doesn't seem to match anything on the following chart.
Mr. N chart doesn't even list a 65-66 rear D60.
So in conclusion... anyone KNOW what bearing end that is?
