well heres the step in strut i was talking about

heres what you need

get the right pitch and tread size and cheaper than getting the standard coil over top nuts to fit.
Toyota celica ones i think they were. $10 a set of 4 from supercheap.
as for the conical spacer washer???? i used some from some subaru struts i had lying around that fit. before that i used high tensile washers of vaious sizes stacked to get the right spacing to let the bearing move.
dodgey buy effective. i greased them slightly too to allow movement so the wheel nuts didnt loosen up if they spun.
the washer sits on that top step below the thread(in my picture the washer was too big and was forced down shock tube shaft (similar to how your struts came through bearing).
the spring top hat sits below that washer. if you had long shanked nuts, you could even possibly install thriust bearing and place washers on top to sit under the pillow ball but then there would be bugger all thread holding shock strut to the wheel nut.... easy to work out once its all apart.
