is this the one?? more pics in gallery

 

Maybe? Measure the spring perches. Anything later then 79 will be wider. Also the 79 d60 has the longer short side axle tube and pot is more centered.

By the way 'ol blue' in your gallery needs the double stacked lift blocks removed under front axle. Little scary. Also steering angles look steep. Crossover should be on the list.
Is this the axle you want to put under it?

 

I junked the ol blue minus the cab and front axle. I put the blue cab on the green machine (other truck in gallery) and want to put this axle under the green truck. Don't know if its a 60 high pinion ,king pin axle.

 

Yep, it's a 78/79 D60.

 

Well if it was under a 73-79 and springs were not outboard(sign of a later axle) and it's kingpin then it's a 78/79 d60.
Next swap ditch the blocks, go crossover steering and might as well flip the front u bolts and make new top plates so the nuts are at the top for clearance. And upgrade to a 5/8 ubolt.Youll have to notch the driver side gusset for u bolt to sit in.

 

It's definitely a 78/79 D60, the DS spring perch is notched (as seen in middle pic).

The later (80's and up) D60's do not have this notch in the DS spring perch.

 

I would like to run like 38's -40's some day. So this is that axle that is highly sought? any links about setting this up? I'm all new at this setting up a 4x4 truck. I have been sitting on this axle for like 5 years. Putting together the green machine in gallery

 

There is alot of info to reserch ,its all there,plenty of folks to help you out.73 Ford Guy already was steering you in the right direction.I just finished my swap.Had the axle on saw horses and tore it all apart ,sandblasted and cleaned it up.Installed it under truck as an empty shell and then began to rebuild.You will see what i mean when you do the reserch,Im glad its done,,,,good luck
