[DeTomaso] Wheels houses

[dickruzzindesign]

Chuck, 
I think you are describing the "wheel openings", the shape on the outside sheetmetal.
The "wheel housings" are the the surfaces that are at a right angle to the cars lengthwise centerline that wraps up and over the wheels front to back, sometimes called the "wheel tubs". The shape of the openings and the tubs do not necessarily mirror each other.

All the best, Dick Ruzzin.
