Ok i am gonna try to explain this as best as i can.
What i am trying/want to do is extend the surrounding of the shift lever surrounding.
Here is a picture of what it looks like original

The silver area left and right of the shift lever is 1 part, then the ashtray above the lever is a 2nd part.
What i want to do is remove the ashtray, and extend the 1st part and give it a small upward curve.
And make something like this picture

So the question is.
How would i go about creating a mold for this.
The original part is flat so getting that in a mold is no problem.
However the new none existing part is the challenge.

And are there any specific components to use for this kind of work?

Afterward i just do a CF finish( car interior is CF original anyway), which i am already familiar with.


Hope i am making sense.

Thanks
