Will a detroit from Chevy or Dodge front low-pinion Dana 60 (35 spline) fit into a Ford front high-pinion Dana 60 (35 spline)? Yes.
For a Dana 60, as long as the spline count matches, the carriers are interchangeable.
One thing you have to realize is that there is only one (stock) carrier for the stock HP Dana 60: 4.10 and (numerically) down.
This means that if you are trying to buy/use a detroit from a Chevy/Dodge 60 you have to use the (numerically) lower carrier. All HP Dana 60 gears that are 4.56 or (numerically) higher are "thick" gears.
All HP Dana 60's must use the same carrier (the numerically lower one).
