Fitting Corsa b shocks to rear advice

[wehey]

Ok. So I finally managed to fit my Matiz springs to the front of my Micra and now it's time to do the rears.
I have a pair of Corsa b shocks for the rear and my understanding is that they may need modifying slightly.
I have tried searching on here but can't find any info.
To save me taking it all apart first can anyone tell me what I need to do to make these fit??
Thanks

you have to shave a mil or so off each side of the bottom bush, and use an m10 bolt

Ahhhhhh.......magic!! Thanks frank. Any idea of bolt length or am I really taking the pish this time lol

Ooh....... Also whilst you are around, will I need to mod (cut) the springs at all to get the height right? If so, how many coils do you recon??
