After searching serveral forums looking for an answer to...... You strike gold and find a thread that is asking the same thing your wondering. Finally, an answer........ But no one came back and finished the thread with the answer (if they found one) it was just left haninging. Damn that's frustrating...
The 16mm Jamming CRT Big Bores fit fine. The ones I got were from e-bay and came with the spacers the Patrick linked to. You'll need them. I have some springs coming in the mail but couldn't wait any longer. Don't remember where the springs came from but the work great. Fit inside the spring retainer and a perfect fit on the bottom of the shock body.
