Put an indicator mark on the ring gear and spin the pinion side by hand.
Less than 4 full revolutions of the pinion side will be 3.73's and slightly over 4 will be 4.10's, a good way to confirm you got what you paid for.
(3.73 revolutions for those gears and 4.1 for that set of gears if not clear)
I don't know the tooth count for these gears, but beings two signs of 3.73 is leaning towards that, do the above to see what you ended up with.

I've got a 3.73 ring and pinion in the garage that I could go compare numbers to, but the above suggestion might be the best way to tell. I am pretty sure mine was stamped with the ratio on it, but that doesn't necessarily mean yours is.
I don't know why I didn't think of doing this trick the other day, when I had them apart. I will try it out, but I am pretty certain I have 3.73s.
I called the junk yard that I bought these axles from. Spoke to the same salesman, he is looking for a set of 4.10s for me. Said he will figure it out and get me what I need.
Saw a 4 cyl KJ being sold on Craigslist for $700 for parts. That would have your 4.10’s. It’s in CT, which might be near you depending on where you are in NY.

Well I am on my 2nd set of axles from a junk yard that were supposed to be 4.10. Both sets i got ended up being 3.73, which are no use up me.
It’s a little disappointing, first I’m getting down to crunch time on a trip. And second, this last set looks great!

In 4.10? You're in Southeastern Ohio, correct? I do get out that way somewhat often. Lets talk.

Just a question, do you think the 4:56 will kill highway mileage? I am running lt265/75r16. I cannot find any 4:10 for the 30a online. It appears Dana Spicer has stopped producing them.

I believe 4:10 is the largest (numerically) ratio that can be put into the 30a. Even if you could find a new one the price would likely cause you to p**p yourself. Do some junkyard searching and pickup an intact front diff you'll save many hundreds of dollars not to mention paying someone to setup your gears.

Well I finally got to tech support at Dana Spicer Ann got a part number 84006-5 (4:10). They are pricey $500 to $900 depending on the vendor. That is just ring and pinion gear no bearings or seals.
Putting them on a open diff shouldn’t be that difficult.
