B6 transmission in B4 possible?

[Avant_quattro]

hi guys!
I'm in a project of rebuilding an Avant Quattro building the body from scratch.
I currently have it in a FWD configuration awaiting a good donor for the Quattro install.

I just got a donor 1.8T20vt Quattro A4 B6, and apart from taking advantage of the seats I'm investigating if I can use the whole rear transmission.

If I get a rear B4 subframe, can I use the differential and driveshaft from the B6, what driveshafts should I use?
actually use S4 B5 front hubs

Let's see if someone can help me
Thanks!

It's not an easy swap. You would have to cut and 're weld various points in the chassis. B6 is very different. B5 was the last version that's almost identical to S2 Avant. Even that has quite a few differences, such as hub size.

Hi guys! I have been evaluating and finally I will sell the B6 and take a B5 quattro as a donor. I will publish updates.
