Les,

I forgot about you. Sorry.
To finnish the story- this DID fix my clunk. I drove my rig around alot this weekend and never heard it. It also seemed to fix alot of my stability problems that I had thought were bad shocks. My rig now feels more steady on the road.

I replaced the front shackle top bushings about a year ago and they still appeared new. The rest of my spring bushings are new too. It was really an easy job and I wish I'da done it a year ago as I was always fearful of that clunk.

Good luck,
-B.
