Le(n)ck transmissions

Hello, guys.

Now it is time, after the steering gear has licked more than 1 year ago (it has temporarily sealed with an oil leak stop) now break all dams and I have to underlay a cardboard box now, since I am constantly losing oil. The work would be too much for me to install a used V8 transmission, which then licks again after a year and costs a new one, I think 700€ That's why I asked what kind of steering gears fit in the V8? Other, of a kind used in the manufacture of motor vehicles of the 200er(100er) or also which of the C4 Audi 100/A6? Does the C4 Quattro models differ? Who knows? Thank you for the information in advance
