What I did is simply drill 2 holes on the original damper plate, then made 2 extensions off of the body posts to attach the Exotek dampers. I used 10k weight grease on the dampers. Also Shimizu makes or made o-rings for the F103 in soft, med and hard and included some double wide rings. I use the hard in the front and the pivot ball in the rear. I have not yet tested this. Also, to center the posts I ground down some front suspension bushings (top hat) and it fit perfectly inside the original hole in the top deck.
