The seat back, or "driver's and gunner's backrest" , mounts seventeen lift-the-dot fasteners. Each fastener has four components when using the threaded post style. Ideally you want a factory punch tool to prepare the material for fitting the female portion.

The male portion of the lift-the-dot can be found in at least two fastening styles. In the posted image you can see one style using the captive threaded post and nut, as well as another style using the flat head countersunk screw style mentioned earlier. The threaded post and nut style is on a 1942 dated board with a stenciled part number C01UC-105801B (see FUC-03 Page 272). The finish on the threaded stud is plated, i.e. it is not anodized like the two components of the top plate. Note the difference in the stud finish on the other board?


The square profile rear seat and kneeling pad, TL 12657/CTL 12657A/CTL 12657B is pictured. This seat pad has a horse-hair filled cushion only, no spring box as found in the driver and gunner seats. As such it is one-third the depth or thickness of the front seats. No wonder they are found double up, with one cushion on top of the other.


When you also compare the size of the backrest for the rear compartment passenger with the backrest used by the driver and gunner, it must have been miserable in the back. The rear backrest is "deeper" in that it measures 1-1/4 inch sides vs the seat backs at 3/4 inch. Beats ground pounding?



The brackets pictured are 1942 dated TL 5061 and TL 5062. They have the double positions for fitting the mounting plate. Unlike the single position bracket C01UC-105802-03 L.H. and R.H. that replaced depleted stock of TL 5061/5062.
