Any ideas or suggestions to the following.
I need to make L & R tail light housings about (8" wide x 4" high x 2" deep) on the back of a street rod I am putting together, unfortunately there is not a flat place back there only compound curves from top to bottom and left to right.
Trust me, I would buy them if I could find them.
The forward portion will need to be machined to the contour the rear portion of the housing will be flat (no problem on the flat side

)
How does one go about getting this contour into a my CAD system.
Any and all thoughts/ suggestion/ideas/opinions/guesses will be appreciated.
Thanks
Ken
