Are you doing it in USA markings?
Most of the decals such as Bell Housing Drain Plug, The small lettering on the guage panel, the black decal for battery ground cable, and air cleaner bonnett, are shown on various pages of TM9-8014. There were no other except 1"TP-25 and Max Fueling Rate and unit markings for the bumper. Later on some vehicles had warning to secure hood in open position stenciled on the inside. Original USA Reg was in 2" with 1" between lines. On the M-38A1 the bottom of the numbers rested at the level of the top opening of the fording hose cut out.
The Gas Can Strap was 1 1/2".
