all GT faceplates will have the lower portion that the radio would go through. EVEN radio delete had that but no holes for the radio

I have seen 1 GT heater only Radio Delete plate in 8 years on the internet looking for 67 Dart parts. AND yes I should have bought it!
I think the only rarer part would be a 67 GT AC/ Radio Delete bezel (if they made one)
