Ah,
I wanted to ask you if you could probably make photos of this 4.2 car you've disassembled - especially, again

, from the interior!
You may have the common Audi V8 4,2 ABH sport seats, or also called post-face-lift seats. They indeed the same ones as in the Ur-S4. Do you have memory?
Could you tell a bit more about the battery and the computer unit under the rear seats?
Manual LHD V8s are rare, but you can find one, probably. Let us know when you start to look for one, probably we can help! Taking a V8 over to the UK should be at least as much fun as taking one back "home" from the UK

Regards
Bastian
