Upsizing Plastic Bushings

I needed to upsize the plastic bushings used for wire runs within the left wing. The use of a heated pitot tube with AOA with the additional wires and two separate 1/4" OD plastic tubing runs meant the factory installed bushings weren't big enough for everything required in the wings. Van's published a handy document discussing options for this and allows up to 5/8" bushings to be used in tooling holes. So I upsized multiple holes to accept a 675-8 bushing with a 5/8" OD and 1/2" ID. A unibit and extensions made it a fairly easy task. After deburring the new bushings were snapped into place. I think I've got everything accounted for in the left wing systems wise and room for it all. My plan is to upsize the bushings in the right wing as well in case I need to add things in the future.
