If you want to be fancy, go to your LHS and get the smallest CF tube that'll let you stick 1/16" music wire into the end. Then cut the z-bends off of your pushrod, scuff them up thoroughly, and epoxy them into the ends of the CF tube about an inch deep. If you're paranoid about the CF tube splitting, wrap the ends with kevlar or CF.
If I didn't make it adjustable, I'd make sure I had it on the plane with the bellcrank and elevator held at neutral when I did this.
Like this -- fancy machined brass or aluminum end caps are heavier than wrapping (but prettier).
