Do you want the diff intact and connected to the final drive gear, or do you want just the separate spider gears/carriers and axel/housing? Shipping will be very different depending on which way.
I have the trans in a storage lock-up, and my car currently occupies all the free space in my small garage, and will until I'm done with engine and suspension maintenance and upgrades... maybe 2 or 3 weeks from now.
I'm thinking $100 for the disassembly work, lost part, and mess clean-up, plus shipping (unless you are coming up this way in the near future... Beloit, WI area).
