Dana 60's differences?
Hey guys. I want to change my 3.31 dana 60 to 3.73 and figured it'd be easier to sway rear ends. I have a line on a '72 camper special rear, but just want to know if there are differences that I should be aware of. Thanks.

Don’t know much, but seems like the spring perches will be narrower for the older 2.5” springs. Might even be welded to the axle in different spots, but I think you’ll be ok there.
Some trucks still used the 34” frame width while most were 38” wide (approx. numbers).
I doubt a 72 would have come with the lower spline count axle shafts, but as with all of the previous thoughts, someone here will know that stuff for sure.
Hope it works out.

Being a Ford E-series van owner for decades, I know the vans used highway gearing for fuel mileage like 3.31:1.
I was reading about the Dana 60 and Dana 61 axles on maybe ? Wikpedia ?
My Ford trekker van has a Dana 61 and internals are all Dana 60. You would have to use a 3.50:1 carrier to run 4.10:1's.
There is a slight difference in back of wheel to back of wheel on the pickups vs the vans.
I cannot remember which was narrower. The E250 & E350 vans had a high GVWR which is surprising.
The camper special should have the biggest drum brakes, maybe 3"-wide shoes.
Spring pads may or may not need to be re-located and shock brackets maybe. Yoke size possible switch.
In my '77 F350 pickup I originally installed 3.50's and switched to 4.10's after a couple of years.
Most of my driving is not freeway treks.
