Wheel Bearings and spindles are the same I believe, it is a strong axle. The aftermarket supports this axle pretty well, it is a much better rear end than a dana 60.

#2 what side is the pumpkin on?
#3 do you know if it's hp, lp, hp is above axle centerline. lp is below.
it's most likely a low pinion and will share the same gear sets as a d70 rear. outers will be either old *** course spline stuff, 17 iirc, or 35 spline depending on what age and what it came from. need a lot more specifics before i can tell you anything more. and some pics would help too if you don't know the specifics.

it from a mid 90's f450 driver drop. probably a quigley conversion guy said it was an 4x4 ambulance conversion.
I figure r and pinions would be expensive. i think its reverse cut whatever that means
King pin Dana 70

i don't recall d70's being used in late model ford apps, but i will admit i don't know it all. you did catch the 10 lug part, right? you do realize you'd need the 10 lug rear out of a similar f450 or f-superduty to match, right?
honestly i'd just look for a d60 front and save myself the hassle. add in the cost of tracking down a matching rear, regearing in you end up with mismatched ratios, and a new set of 10 lug rims and you are talking big money for no real major gain. also pretty sure the 10 lug rims kind of limit you to 19.5'' and bigger h/d rims.
EDIT: also that axle is most likely a dually axle if that matters to you and your application.

i have 3 of these old f superduty trucks 
. all 5.13. the older ones were
10 lug 235/85 16"
I think the ten lug thing is just a spacer maybe 8x6.5 to whatever it is i'm not sure. yeah maybe be cheaper to get a 60 and have spacers made unless that diff is 5.13.
guy doesn't know what the gearing is.
But are u correct that the ring pinion is standard cut like a rear axle??

^^^This
Most commonly seen d70 fronts are not very desirable. The only real world benefit over a d60 with 35sp outers would be the ring gear. I would never go through the hassle bc its not a stronger axle.
If you need more than a d60 with upgraded shafts then you need to step it up to rocks.

He said it was a quigley conversion ********^^ :flip
Depending on what you're using it for there may be better choices than rocks, but it will most likely have to be custom and custom = $$$ if you aren't doing it yourself. What's the application?

an OBS f-superduty. 2wd same model truck it came out of. but im wondering what to do about ebrake since mine has a drum on back of transmission. and if i ever wanted to change gear ratio my rear axle has 5.13. I don't know whats in the one that dude has.
I think a dana 70 front has 35 spline outers low pinion but ring and pinion i may have to go to dealer. maybe ill offer the guy 500 if it has 5.13 other than that better off going with d60 maybe ill have to run different rims 8 lug on front ten on back or fork up for some wheel adapters by fred goeske or similar.
What does rocks mean?? rockwell??
