Just be careful when opening a plastic clevice with a screwdriver... (or knife) All too easy to damage the clevice pin. The metal clevices are better.

Note you NEED the 1/4 inch of fuel tube on any clevice to keep it locked on the control horn. If the load on the clevce is not 100% straight line down the pushrod, it can pop off if you don't have the piece of tube on it. (and the loads are NEVER perfectly straight down the rod.)
