[Shotimes] Rear suspension rattle

Greeting Fellow SHO Fans

I recently did some suspension upgrades in my 1994 MTX SHO.  It was an interesting journey especially when I sheared the the head off the first pinch bolt.  If you ever do this I would strongly recommend heating the knuckle before attempting removal!   This will save you a lot of aggravation.

I installed Eibach springs, new KYB boots, KYB strut mounts, and Koni inserts.  I have found this upgrade to dramatically improve the ride control of the car and except for the problem below am pleased.

I found when I installed the Koni inserts into the old strut tower there was a surprising gap between the old and new part.   This was due to the diameter of the new koni being smaller then the diameter of the original strut.   I put it together with the rubber boot supplied over the old strut and around the koni.  This left the gap inside but sealed it from the elements.  

I am commenting on this because I now hear a rattling sound from one side of the car in particular and am wondering it this is due to that gap.  It is hear especially while braking and on a bumpy surface.  Has anyone had this happen?  Everything appears to be tight top to bottom from my upgrade.   The only think I can think of is this gap and the old strut slapping against the outer portion of the koni.  I am wishing I had either filled the gap with silicone and let it cure or put in some kind of rubber material to fill it.

Information would be appreciated if this a possibility or another possible cause.
