all you'll need is to fab a new bracket or re-fab an existing b5 bracket. not too hard if yo know how to weld

 

Welding and fabricating I can do, does any one have a good picture of the current seat bracket in a b5.5. It looks like the stock track of the b5.5 is similar to the mk4 track that uses a single rail down the center. The TT seats have two ralis that mount to either side of the floor. Keep the ideas coming

 

b5.5 has a two tracks. you might have to buy a aftermarket slider and custom fit the seat to the bracket. i bought a corbeau bracket for 75.00 from the manufacture. shouldn't be to dificult

 

There is no plug and play swap in the VW\Audi line?
Oh learned ones, tell me it is not so?

The mkiv sliders (that the TT uses) are narrower, so are the ones from the A4. Most you could do is replace the sliders that are mounted in your car with ones from the TT.

 

stated above...all you need is a seat bracket and weld away
