99 Cobra pumpkin in Mark 8, IRS. Help please

[Dlachance]

I picked up a 1999 cobra rear pumpkin with 3.55 gears to go in my Mark Viii; it currently has an open diff and 2.73's. I want to just swap the unit instead of gears. Can someone post a link or let me know what all is involved? I have never worked on an IRS car, only SRA stangs. Also, will I be able to use the stock M8 driveshaft? A write up would be grand, but ANY info would be great!

Thanks!

Are there any seals or gaskets I will need? What fluid will be best to put in? Thanks.
