Rear strut Koni problems

[wikan]

Afternoon all.
Went to to replace rear struts with Koni's.
All apart, come to find out the Koni's change size about 1/4 inch up from the bottom of the strut. Will not fit into the bearing carrier housing because of this. 2003 Boxster base..
Has anyone else had this problem?/ If so, how did you solve?? Am about ready to put the old ones back in!!!
thanks in advance
