saloon / estate b6 / b7 will fit, front seats and doorcards are the same, the only thing to check is the rear seats if you have split folding then you have to buy a split folding rear or if you have a solid bench seat (non folding) you have to get a solid bench seat, unless you know a good welder and fabricator but it is alot of messing about to get split folding rears seats in a car that had a solid rear seat.
As for a cab the front seats should be ok, but doubt the rear seats would fit at all as they are a different shape,
