70. Thread the screw into the wheel mount arm. Make sure not
to overtighten the screw, preventing the wheel from rotating.
Use an M3 x 4 setscrew and 1.5mm hex wrench to secure
the screw to the arm. Use a drop of threadlock on both the
screw and setscrew before tightening.
71. Place the gear door linkage mount near the indentation on the
gear door. Transfer the locations for the mounting screws to
the gear door.
72. Use a pin vise and 1/8-inch (3mm) drill bit to drill the holes
for the linkage mount in the door. Make sure the holes are
centered vertically in the indentation.
73. Mount the linkage mount to the gear door using two M2.5 x 5
button head cap screws and 2mm hex wrench.
74. Attach the linkages to the linkage mount using two M2.5 x 8
button head cap screws and a 2mm hex wrench. Make sure
the linkages can move freely when attached to the mount.

installation in the P-51D Mustang.
75. Use a hobby knife with a #11 blade to remove the covering
exposing the mounts for the fi xed landing gear.
76. Slide the strut mounting stud into the landing gear mount.
Use an M3 x 6 setscrews and 2mm hex wrench to secure the
stud in the mount. Tighten the setscrew onto the fl at area on
the stud. The end of the stud will protrude 1/16 inch (1.5mm)
from the end of the mount. Use threadlock on the setscrew to
prevent it from vibrating loose.
77. Secure the landing gear mount using four M3 x 20 socket
head cap screws. Make sure to place a drop of threadlock on
each screw before placing them in position. Use a 3mm hex
wrench to tighten the screws.
78. Slide the strut on the landing gear wire. Use three M3 x 3
setscrews and a 1.5mm hex wrench to temporarily attach the
strut to the stud..
79. Check that there is a slight amount of toe-in (approximately
1-degree). Adjustments can be made by loosening the three
setscrews on the strut near the mount using a 1.5mm hex
wrench.
 The amount of toe-in shown has been
exaggerated so it can be seen clearly in the photo.
 Always use threadlock on metal-to-metal fasteners.
