Hello all

im in the process of making adjustments to the boot of my 3 door A3 to accept a full size spare wheel it’s been quite a challenge but im nearly there just have a quick question about the screw down clamp that used to hold the space saver wheel how is the fixed part of the clamp assembly attached to the floor of the boot I cant see how it’s attached as i want to remove it and get a clamp to secure the full size spare wheel

any help much appreciated 

Thought id post a pic of it as well

does anyone know if you can buy the dark grey cloth that covers the spare wheel cover and if so where would i buy some 

many thx again
