Hit a bit of a problem in my 76 f350 dana 70 f350 diff build up. Stuck way down in Australia where people dont know a lot about these things.

I have been told i need to change down from 5/8 to 9/16 studs to suit the wheels i have ordered.

So i need the 5/8 shank with the 9/16 thread, Anyone had experience with this?

Even better anyone got a part number and supplier?

Thanks

 

Ive run into this with a newer truck , looked and looked for a part number have yet to find anything .
Dorman "pic a nut" should c

 

Should show something .
( stupid iPhone double text )

 

may have to drill out the wheels or change hubs... could also try a bolt on spacer.

 

spacers are illegal in aus sadly, might have to change hubs but thats an expensive option, i dont think drilling the wheel will work either sadly, its more about where the wheel nut countersinks into than the bore. Ill keep at it, and if anyone knows any info please let me know

 

Are 70 hubs different from 60 hubs? I think both my 70's had the 5/8 studs but I think the 60 I had was 9/16's. Just off the top of my head I think someone told me the 70 and 60 used the same bearings and hubs. The local junkyard has a 60 that still has the hubs.

 

i think the rears are different, not sure, but i didn't think there were any dana 60 dually diffs, hmmm

 

the 70's on the duallies were the same width as srw duallies.
