If the dana 60-3 has 5 lugs and a lower GVWR rating, how much weaker is the rearend as far as ability to handle power? does it have smaller bearings or pinions? what other than the lugs is and that it's semi floating is different between it and a regular Dana?
I don't believe the center section (the Dana unit itself)is any weaker than the F-250 unit. The weakness comes form the lighter duty outer axle bearings. Going from double tinken bearings and a full floater axle to a single race ball bearing will cost you in terms of load capacity. Also the older Dana 60-3 probably used the 16 square cut spline axle shafts( just speculation as this was the standard spline count on the full floaters). The center section should be the same as any other Dana 60. I believe Ford used the Dana's for the limited slip rears in the pick ups because they felt the 9" didn't have as strong a posi-unit suitable for truck use.Any body know for sure?

True, But that was by '69. Prior to that Ford thought they didn't have a strong enough unit for the trucks. So they used that '*******' units the Dana 60-3 and the 44-3. Technology does improve and the 9" got a better unit to allow it to be equiped with the Limited-slip.

in the late sixties and early seventys Ford sold the 427 and 429 CJ and Boss engines in the crate, just like they sell engines now. Back then, before emmissions concerns and liability fears overtook us, there were some Ford deaalers willing to put together anything your little heart desired, if you were paying for it, they don't want to lose any customers. They were well aware if they did not do it for you someone else would get your $$$, their greatest fear. As for any of these being installed at the factory, it was probably not intentional. Having worked on a large assembly line before, the company's greatest fear is that the line will stop, (less $$$). We have used whatever was instock to keep things running, as long as the pieces fit. I would have to believe Ford production lines aren't any different.Whose to say some smartaleck line worker didn't put a 427 where a 360 should have been? Just because he thought it would be neat. I've often wondered why I see so many FEs with car style oil pans, even at the dealer's, in 4wd trucks. Laziness? Expedience? DF
The Dana 60 was never offered in a Ford with 5 lugs! Don't bother sending messages about me being wrong. Send a picture! I bet that If there is a truck with a 5 lug Dana, that it came out of a Chrysler car! It never happend from the factory, or a dealer! Pctures please!

The factory 427 is a "pig in a poke", but the Dana 60-3 with 5 lugs isn't. Here's an image from the Master Truck Part Catalog:[/FONT]
Richard, aka merc66, has a 5-bolt Dana 60 under his just restored 66Merc Ranger and it has always been there. He didn't believe it either - he thought it was a 44 - until the cast-in "60" was pointed out to him.
