Finished pilot and copilot master cylinder install except for the AN3-7 bolt I need to order to replace the AN3-7A. Tested and decided to swap the position of the two bushings on the return spring assembly so the higher load one is on the end that moves. This matches the vansairforce picture, but not the order of the parts on the parts list. Reworked the pilot master cylinder install with the bushing swap. Adjusted all four of the spring retaining collar to have a 1/8" gap between it and the master cylinder mounting tab on the rudder bar.

Considered different options for which grommets and which hole pattern locations would work best for the brake and fuel line routing through the F-782B-R/L brackets and through the landing gear mounts.
