So I just bought a pumpkin from someone with the stub shafts pulled out(but i have them on the side). He says the pumpkin is off his G37 and it is a vlsd. Without taking it all apart, is there any way to confirm that is is a vlsd or open diff? maybe by looking at the stub shafts?
Also, is there any way to confirm its a 3.7fd?
any help appreciated. I searched but couldnt find anything definitive.

Thanks Trav! seems to be legit then. I think the viscous coupler in the diff is going, but I got a deal on it so I will be using it anyway for now..
I have a 3.3vlsd as I did a 6mt swap, so this would be quite an improvement for me.
Now I just have to figure out how to get the stub shafts back in without breaking anything! lol

They don't push in by hand, I use a 5 pound dead blow to tap them in.

I got it to go in.. it was weird; short side went in decently easy, but last inch I had to hammer the crap out of it... Long side was the same... then once it was in, since there are no circlips, the long side now goes in and out very easily. I ordered circlips and will put those in before installing the diff.

yup its still out of the car. and it slipped in fine without the circlip on. One side always gets stuck for some reason.. i had it together without the clips and the short side was hard to remove but the long side slid in and out easily.. as soon as I put the clip on, the long side slides in til it hits the clip, then won't go further. Even with "persuasion".
I just don't want to mess it up. Pretty sure it looks to be: Short=passenger, long=driver side. Please correct me if that's wrong.

So I am not an expert (had an expert shop put in my quaife), but aren't the circlips the only thing that keep the stubs in the differential. I thought they fit in a groove in the gears in the differential. So I am not certain you want to be hammering them with them on. I always figured you put them in and then put the clip on with the back cover removed. But I could be wrong! Also the reason sometimes they go in easy and sometimes not, is I figure they aren't exactly lined up with the gears inside. I figure you would need to rotate the input shaft slightly while wiggling it in, but again, that is just what I would guess based on my understanding of how the thing works.

I can get the long stub shaft to feed in and line up with the teeth, but it stops right at the circlip. I am not 100% sure either as it was taken apart when I got it, but it looks like everyone(in other posts) puts the circlips on the shaft then puts the stub shafts in.
I am also not 100% sure which stub goes in which side but it looks like short=driver side and long=passenger side.
I hope someone who knows more about it can chime in as well before I start going to town on it with a 20lb sledge. If need be, I can open it up and do that. I am just not sure tbh.
