Greg, you keep talking about the Kirby car as if it started life as a DH car, and DH designed and built it...quite the contrary...it becoming a DH car was WELL after the fact. DH had no input on the building of that car, other than the fact that Dickie gave Kirby a blown engine in exchange for Kirby painting it up as a DH car.
And I still say the car in
this picture has bolt in tail lights...
