Those who have changed the rear stroke, what are you running? Where did you get the hardware?

I'm running a 2.0" stroke Stratos Helix Expert, but I'd really like to have more options. It won't last forever and I don't know of anyone rebuilding these.

I'm thinking of buying a 7.875 x 2.0 shock of some sort and having a perch/trunion fabbed up, but that probably won't be easy.

LONG LIVE THE LAWWILL!!!!
