i am having a few problems with the rear shox`s on my rs200 replica

here is a pic of the top mounting points that are on my chassis at the mo

if i use these to hang my coil-overs of,the bottom of them wants to be right in the middle of the wishbone bottom spring perch`s.


if i use the orignal bottom mounting points on the wishbones i can make a mounting point on the chassis.

with the shox fitted into the lower mounting i have about 20mm clearance from the rim face to the spring.



which 1 would be best?
if it`s the orignal mountings on the wishbones at what angle would be best to mount it,vertical,angled 1 way or the other

sorry if this a long thread but i only wanna do it once and be sure it is correct,and suspension tech ain`t my thing
thanks
