Thanks, it is a good idea, I did not think about it, and I have I lot of left over Tamiya decal
Tamiya's would not help... their "2" is of a different era when the numbers were smaller in real world. The problem is that hiding a 1 with a greater 1 is easy, but the 2 is trickier.
Probably Michael Indycals has proper sized number 2.
According my measures (and Protar's) number sohuld be 10.8mm tall
