Need a FMV - broken diff and some axles

Would like to get this on my books. For the bike-engined fiat we plan to use a diff carrier and stub axles from an infinity j30. The diff we are using is coming from a team member who used it in his LS-swapped 240sx. I think he paid $100 or $150 for the diff and axles a few yeas back but has since driven it a lot and torched a bearing or something. The diff is broken now (he's broken a few, this one is either missing some teeth on the ring gear or is whining really loudly, he didn't know which was which when we grabbed it from his pile, and I haven't torn it down yet) and he has replaced it with a good one. 

My local LKQ shows price of $119.99 + 25 core for an entire IRS rear axle assembly d-to-d. But that would theoretically include disks/hubs/bearings that we aren't using. And that is assuming a used but still working diff. 25.99 for a CV axle. There might be cheaper yards around but that's an easy price list to grab. 

So what is FMV on a broken diff and two used CV axles? The diff does have VSLD (which we want) but even working ones are cheap. 

Call it $60 for two $25 axles and $10 scrap for the pumpkin? More? Less? What do you think?

I think you’re being fair at 60.  For reference i was given a free 370z center section with lsd because of a bad pinion bearing

I would agree that $60 is definitely fair. 

My local pull-a-part lists 68.85 +$8 core for any differential, but yours is broken, so maybe call it $40 for a broken one (roughly half junkyard price). 25 per axle sounds fair too and is also what my yard charges.

As another data point, I sold the open diff out of my Infiniti donor car for $50 cash on facebook, and that was in working condition. I bought a working VLSD on craigslist for $125.

$40 for a broken VLSD sounds fair to me, but it better turn out to be broken or I'll be jealous of that deal!

EDIT: just read the other responses. I could settle for $20 for the diff.
