Don't hate me because i'm beautiful
I'm curious too.
What did you end up paying for it and is it a clutch type or a cone type?

That's a clutch type.
Before I did any setup, I'd put bearings on it, put it in a naked case, and check ring gear runout. (With a dial indicator)
I believe factory spec for a factory carrier is around .001. I sure would like to see less than. 004.
Edit: I believe Dr Diff sells those as well, with upgraded internals and clutches.

I was about a day away from buying one of those when I found a rebuilt "old" clutch type for about $20 more locally. I will be watching this because if it works out for you, I will end up getting one in the future

I can fix stupid, but it's gonna hurt...
$181.09, delivered to my door.

It's gonna be going in the case as soon as I get the bearing kit from Cass. I'll check runout and get back to everyone.

Good! Keep us informed.
I've got a 3.55 open begging for a cheap "posi" lol.

If you have access to a lathe, I'd be tempted to chuck it up to check it for runout and give it a skim pass to clean it up if needed.
.004 in any of my carriers would not
work for me.
work for me.

I'm hoping that he misplaced the decimal point and really meant 0.0004". Four thousandths is a mile more than four ten-thousandths when you are looking at bearings and gear lash.
That’s my test mule ! And a 4sp for good measure .500 foot pounds of torque and a set of good drag radials to let you know if it's any good pretty quick.

Luckily I'm only guessing maybe 350-400 ft/lbs., so if it's close to concentric and decent metal it will be fine.500 foot pounds of torque and a set of good drag radials to let you know if it's any good pretty quick.
Yes I've seen those advertised definitely a good price. Love to hear report from The trenches.

i did order one of these units when they first hit the market , to see what they are like as the price is unbelievable and being a Chinese knock off they have flooded the market ,, the unit itself looks ok , runout came in at 0.0015 so good there ,, BUT ,,, i notice that there is no HEAT TREAT ( case hardening ) on the case where the cross pins sit in the ramps to reduce wear at those 4 points which the factory cases and better aftermarket units have , and upon taking it apart the clutches used look crude as there is a lot of mill scale from heat treat on them NOT SMOOTH like the factory clutches or even the replacement Mopar Performance clutches or the Spicer kits ,, the turning torque for the unit was at 100 lbs/feet so the clutches may not last as the heat treat may be off. as far as the side gears and spider gears they look good but are they heat treated properly , who knows ,,,,, i build a lot of differentials and use the better units , pricier , but i am more comfortable with them. so i RETURNED the Chinese unit ,, price wise they can't be beat but will they last in a car that is driven a little more robustly , time will tell i guess.

I do not buy foreign products whenever possible. I'm willing to pay more for better quality and to support American jobs.

Screw the runout, what the hell did they cast that out of, failed hopes and dreams? I've seen better cast iron produced at a Renaissance Fair.
I get it that these are expensive parts, but are you really willing to trash a ring and pinion and bearings and possibly a housing because Yang Lau didn't think some sand floating in the cast iron was a problem?
Jeez man, a fool and a money. Seriously, look at the machined surfaces.....what cutting tools are they using? Broken beer bottles?
Look at the difference in machining, material uniformity, casting precision, etc....
Look at where the bearings press on. Look at the smoothness of the as-cast surfaces.
Good price on eBay? Nooooo. Bad price on utter garbage.
