| X.4075. Extract from R1/M20.9.22. (3) CHASSIS WIRING - GOSHAWK. I agree that the Simplex joints and tubing are unsuitable for chassis work, and I recommend for trial pieces of straight tube for carrying the wiring in the chassis frame with no tee or elbow joints, but beaded or slightly bell-mouted ends to the tubes. | ||
