98' a6 quattro

Hi all , anyone know where to get the hub bolt socket and size?
also what mm is the 12 point hex to remove inner 6 bolts from tranny?
Thanks!

 

The triple-square (XZN or Double-Hex) socket bit is a 10M.
Try to find the long version, although O'Reillys - and some AutoZone stores (the one in my town doesn't) carry the shorter version which comes in a set of 4 (Performance Tools - brand).
I bought mine on Ebay for like 10.95 shipping included, but afterward I saw it at O'reillys for $ 4.99. Probably they just added it at the time as a new part in their inventory...
It looks the same as this set, although packaged by PerformanceTool.

You can buy the longer version as a set of 3 pcs - ZDMAK via Ebay, or if you have money to burn you can get a heftier set - Autodax.com.
There are some other places selling a long set, like SjDiscountTools, Metalnerd, etc, but I found the ZDmak as being the better deal.
