aileron connecting rods between the struts. Put the handle
top onto the part of the handle holding the struts and place
the completed handle on top of the cabanes. Secure the
handle to the cabanes with four 4-40 x 3/4" [19mm] socket
head cap screws and #4 flat washers. This is how the
completed handle looks when you are storing the parts or
taking the plane to the field.

mount (inverted) to the firewall with four 8-32 x 1-1/4" [32mm]

the firewall to the front of the thrust washer measures 6-1/4"
