Jason,
If you look closely at the Classic Parts and Chevs of the 40s links you provided you will see that the decals are for multiple years. The only decal that pertains to your 1950 vehicle with the Fresh Air Heater is the small "Defroster" decal and it does not go on the heater assembly itself, but rather on the defroster cable mount under the dash to the left of the steering wheel. I believe the letters are white which is the proper color. The decal application will not include the colored background. Hope this helps,
Kent
You are absolutely right and now it all makes sense. Thanks so much to you and everyone that posted on this!
