VW Transporter B14 rear adjuster kit

I have the following BILSTEIN B3 REAR SPRING - 36-196050 which I got by mistake instead of the ones for standard suspension. I am not debating between changing the springs or getting the ride height adjusters fitted on. But you do not seem to be selling the adjusters for Audi TT. They seem to come only as part of a bundle with front and rear coilover kits.
Are those the same?
Could you sell the adjuster for Audi TT separately if not? See more »
