I know Archer: http://www.archertransfers.com/ do 1/35 dry transfer decals for U.S gauges, so there maybe something there. IRC, the Tamiya model has raised dials that are normally painted. Eduard and E.T model also do a 1/35 etch set, not sure about the E.T set but the Eduard S.A.S 1/35 comes with a dashboard. Another route is to source the dials you require and then save the picture and print out on decal paper, that way you can get the size right.
