So part no# 4F0412109 is the bush that's fitted to the top mount. And it seems it's the same for the bottom spring seat bush.
But it seems that you can't actually purchase part no# 4F0412109!! Strange!!
Apparently I have to buy part no# 4F0412066 which is the metal spring seat and includes part no#4F0412109 ( 1 part no# for 2 parts)!! which I dont need.
So am I really having to buy 4F0412066 for the part I need "4F0412109"
Is there anyone that's fitted Bilstein's that could shed some light on this as I'm baffled. Bilstein include the metal spring seat disk but not the rubber bush, A
