I had one o-ring and one 1mm(.040) spacer in the shock. I could not get them tight enough and was constantly finding oil on the shocks.
To run 2 o-rings I would put in an o-ring, a .5mm spacer, another oring. That's about .140" vs the stock x-ring that is .090 or so. In order to keep the pre-load on the o-rings consistent I would put add .045" x .390" shim under the threaded portion of the shock cap, not inside the cap with the o-rings.
