[s-cars] S6 Steering wheel in S4 ?

[RM]

I know this has been covered in the past, with me asking the same very question. Someone somewhere provided me with a link to do the swap but i've since lost that. I'd like to read it to convince myself not to undertake the project (though i don't rem. it being all that difficult). There's been a few on Ebay lately and this sounds like possibly a good spring-time project, once i stash the  S4 for the warm months. Thanks, and sorry for the redundant post :-).
