Another RS4 b7 conversion help required

Hi all
Sorry to admin/mods if this is in the wrong section, ok i've used the search tool for what i need help with but no definate answers as to my query so here goes.

I currently have a 3.0dti Quattro avant and i'm planning on doing a rs4 body conversion sometime soon i've got most parts ready, and please before people start posting "why not just buy a rs4?" i had the car very cheap and it's for towing my other cars about so need plenty of torque and fuel economy.

So now that's out of the way the question is what brackets i been reading about do i need?, there's no definate answers and i've been on audionlineparts but they don't do a avant version.
If you could post part no's that would be great.

Thanks Damien

Thanks for reply Nilz, haha funny enough i spoke to David for a solid hour the other week before this thread was created and although he was planning on doing this conversation himself to a saloon he couldn't remember what brackets was needed.

I've just signed up to audisrs forum so hoping that someone on there will be able to point me in the right direction once i've created a thread, nothing wrong with this forum just think that the conversion side is a big costly job that only a few would even tackle so very little info on the matter.

However, when i get the info i need i'll post up details on this thread and project thread for others in the future.

Thanks mate, yeah i've posted in the audisrs forum in the welcome section and a thread about the hidden parts that i'd also need and not 1 reply or even a hi from anyone. Maybe it's a bit early for a reply or what i'm thinking a bit of snobbery because it's not a rs4/s4 model.

I've now gone down the route of looking at audionlineparts and compare part no's to see if they're different, the only problem is the U.S. didn't have the rs4 avant so can't check any part no's on the rear section.

Have you heard of anyone on here with a UK Audi parts catalogue software that i could purchase?, i'd rather check myself than travel a hour one way to my nearest Audi dealers and spend over 2/3hours comparing part no's and being a pain in the a*se haha.
