Swap B5 and B6 springs??
 

I tried the search and found nothing but I am sure its not a common question either. I work at an Audi dealership and we took a02 A4 3.0 Quattro Avanton trade. It is pretty darn low but I have no idea what springs are under it. They may be lowering springsor they might be the sport springs.I have 99 A4 2.8 Quattro Sedan. Can I have the guys in the shop swap out the springs or are they totally different?? I didnt want him to get it on the rack to swap them out and find out they cant be switched and me look stupid.

Thanks for any help.
