Quick help with ending ebay auction.

[Slippy_Trippy]

I am looking at this diff centre

Holden HSV 3.70 diff gear set & LSD centre IRS VS VT VU - eBay Other Performance Parts, Performance Parts, Car Parts, Accessories, Cars, Bikes, Boats. (end time 11-Jul-09 19:00:14 AEST)

Would it fit my car and what else would I need?
How much should one generally pay for this?
How do just check or do you need to check for wear? Does this look work from the pictures?

Cheers guys
