Not a for sale post! It may come for sale in near future.

I have a 1970, 741 case third member with 3.23 gears, and cone style sure grip. A section of the gears that was above the oil has some minor rust on it. I spent 10 minutes on that with WD-40 and a Scotch Brite pad, comes off with very little effort. The unit rotates freely, smoothly, and quietly. I have no concern that this isn't a fully usable unit as is.

What would be a realistic value on this?

The rust appears worse in photos than in person.

Around me in Wisconsin i see suregrips from anywhere from $100-350 dependent on gear ratio we have alot of 3.55-4.11 around here those ratios run closer to the $350 range.
 
I must say, I'm surprised by the answers so far. Where I live the gear case alone is $200.
 
It used to be that anything in the 2 ratio was about $250, 3:23 was $300, 3:55 was $350, 3:91 was $400 and 4:10 was $450. Add for inflation, and a 3:23 should be $350-$400. The 741 and the cone SG hurts the value, except to those in the know who don’t believe in the myth, so I don’t mind running them if I have them.
 
like stated it being a 741 and a cone sure grip hurts it some but the 3.23 is very desirable.. i'd be asking $500 and see what it brings..
 
50$, trucks and vans out in the junkyard. But that was a few years ago. I'm sure they went up.. and, I'm sure there's less to chose from.... probably way less

That was right in line with what I was thinking.
 
Rust on gear wear surface makes it a core case and sure grip unit.

Potentially needs additional parts cost of gears, and labor cost of assembly.

$500 minus $200= $300 ...$200 ->actual parts+labor will much be more, but you are getting new gears and fresh setup.

Sure that rust MAY not cause and issue. But the buyer is completely taking a chance with that. Even if it cleans up, there are pits left on the fine surface of the gear.
 
I had one like this 5-6 years ago. Took it to a guy who rebuilds them and asked his opinion about it.
He told me to run it, change the oil after 100-200 miles, then add fresh oil and additive.
When I pulled it for the oil change it looked a lot better. I’ve had it in and out a few times to try other ratios but always go back to the 3:23 and it looks really good.
I’ve been running it ever since. No issues.
If you have the time, I suggest running it and do the same advice as I was given.
If you still want to sell it, it will be easier in my opinion.
I wish you the best.
 
The value really depends upon how much you actually know about the unit and are willing to put your reputation on as a seller.
If you have actually used the differential and can vouch that the cone sure grip works, the gears and bearings are quite and it is 100% reliable and functional then it has a value in the higher end of what is mentioned above.
However if all you know about the differential is what you can see and what we can see in the photos, then the unit is basically a core and has a value in the lower end of what is listed.
That is how I would look at it as a seller or a buyer.
 
Thanks to all that replied. I have sold it locally for $380 as is. Buyer has been made aware of current condition, as well as unknowns.
 
I think that $380 is a fair price, for both buyer and seller. I think I would have given that, but would have offered $300. I would have been very happy at $300.
