hmm I got it after searching a lot... Its the 1967 Stout dash emblem, here is an photo of the dash where on the right side emblem is sticked. But i am not sure you can buy a new one because they are very rare. but I think you can get it from some scrap.. here is photo.
The lite stout RK40, RK43 version as the US RK41 had the standard RK45, RK47, RK100 and RK101 1960-1973? Stout item as 1974-78 RK101 had a slightly different vinyl foam coated dash. And 1974-78
Any laser-cutting or CNC shops could make one up for you, however you would need someone to draw up the design first.
