I have a '71 Road Runner with a 383. I have a question about the engine call out on the hood inserts. The numbers are white reflective, but what about the black background? My car had (not original decals) gloss black background and reflective white numbers. What is correct? I ordered a set from Performance Car Graphics and they sent reflective black background and reflective white numbers. To me, it looks like at night when the light hits it, all you will see is white.
