Why dick around with either and run the 70, its a 10.5" ring gear and has the same outer dimensions as a 60. I found one that has 1/2" thick 3.5" diameter tubes that weighed 58# when cut down to size. The 9" pinion is smaller than a dana 44, it only has a 3rd bearing to reduce flex. Nines are just puny compared to a real axle..Tim
Yep, a 9" Ford rear is a POS. That's why it is under 99% of the FAST race cars on the planet 
Leon, you can brag about never bending your Dana housing all you want. But if you put a drag radial on that car you will bend it like a pretzel. And it has NOTHING to do with the stronger center part of the housing, it has to do with the UNBRACED tubes. What, you think the mild steel YOUR tubes are made of is magic compared to other types of mild steel
Mopar guys ALWAYS get their freaking panties in a wad if somebody disses the MIGHTY Dana.........which is a company by the way, that is NOT and NEVER was a part of Chrysler.
Again it is all about the intended application. as to which diff you need. Me personally, I don't care if it came from a Mopar, a Chevy, a Ford, a Nash or a damn VW, I just want parts that WORK.
Now again, does EVERY car on the planet need a Ford, or even a DANA rear..........the answer is NO. But for the type cars I personally work with, the answer is YES on the Ford because it is the ONLY one that WORKS.
The stuff people say before they think, just simply amazes me.

I am running a 8 3/4 and has been good for about 100 passes, Not a real fast car but its heavy and on drag radials. This stroked big block seems to make some pretty good torque down low. I have a truck Dana sitting in my garage but after going back and forth on rear ends I think I will end up with a 9" if this old 8 3/4 decides to go. There is more gear choices for the 9" and just a lot more aftermarket parts available. The other thing is that 60 is a heavy chunk of steel. Who on here doesnt want to save some weight?

I have a Moser Dana 60 under my hemicuda. Put it in there in 2003 after grenading the 8.75 running mid 10s at 3700 lbs. The car ran mid 9s starting in 2006 and now it's a little faster...would like to see 8s soon.
I've had the rear cover off once...last fall. Just to change the gear oil b/c I realized it had been 10 years.
My car is over 3800 lbs, drag radials, leaf springs, footbraking, etc.
Back in '03 I think I paid about $1800 for the Moser 60. 35 spline axles, spool, 4.10 gear.
The dana gets the nod for my cars for cost versus strength. I built a dana 60 for my dad's '69 road runner. Less than a grand in the whole thing...35 spline axles, powerlock diff, 1350 yoke, etc. Built it from a junkyard truck rear.
If I was starting from scratch and building a FAST car, I'd go w/ a 9". Less weight, VERY strong, and any gear ratio imaginable is available. I would start w/ an aftermarket fabbed housing and big bolt through aluminum case. It wouldn't be cheap, but you'd have one heck of a rear.

I don't have a good mental picture of the failure points in a 60.
Can someone explain why the tubes can't be braced?

you wont loose a tire with a regular 9" they are bolted to the flange

Tell that to my buddy who broke an axle at the bearing on his Omni/Charger and destroyed the rear quarter.

Exactly, I've personally seen multiple 9"s break axles outside the bearing. And another thing, why is it at every drag meeting, when you walk around the pits sooner or later you will see it, laying on the grass a 9" pinion still attatched to the drive shaft?????

in all my years of racing I have never seen one break on the outside.

There's the deal right there. A stock Dana will live a lot of places a stock 9" won't. Once everything is fortified with high end center sections and fabbed housings it's a different story.

 In stock form the 9" is no better than a 8 3/4 IMO. I broke two of them in an anemic 79 Ford F-150, no it didn't have giant tires either. I've always said that if the 9" as it came from the factory was the greatest Ford wouldn't have used a Dana in their 3/4 and 1 ton trucks and vans. With all the aftermarket support it has it's a great rear. Application, application, application  .
BTW Quicktree, the axle that broke on the Omni/Charger was either a Moser or Strange, I don't remember which now.

There was NO mention of stock part survivability for either rear in the OP's question, so why is it even in the conversation?
I have a 9" in my Road Runner. I cut and backbraced a junk yard housing, then put together a new center section using a new Strange iron center, Detroit Locker, etc... all good parts. Most new and some barely used, I have about a Grand in the center section. Im also using new Moser Axles. All in total, I have about $1800 into it.
I went with the 9" because I like the way the look, all backbraced etc.... also to have ease of gear change........one center for track, one for street.
