1967/1968 Dick Harrell funny cars

[Jeff H]

Hey guys, I have a question about these "opening door" cars. How did they create the opening door? I would think the body did not come with the opening door but was a solid 1 piece body. Therefore, wouldn't the opening door need to be done once the body was delivered? Larson's car had an opening door and it was a different mold than the DH car. Is it possible that when the DH 68 car first arrived in it's red/black configuration that it was a solid 1 piece body and then when it was repainted could the door have been made functional? I know, this is a wild and crazy thought but Im just trying to figure out the timeline of the car being red/black, then all red, then the tri-color and it having the opening door in the end. Does anyone have that video clip showing Dick getting out the door?
