Would be a waste of time applying the full scale aerodynamic template to it, as it's a total fail.
If you inspect Hoerner's 'AERODYNAMIC DRAG',his treatment of canopies and blisters(pontoon fenders and separate greenhouse) actually goes in the other direction.
Instead of a 5:1 fineness ratio,he'll recommend 10:1.
It has to do with interference drag and super-velocities created by these individual elements when placed in proximity to one another.
This is a reason for keeping the aerodynamic 'singularity' of the 'Template' half-body rather than 'combination-forms.'
Since the half-body doesn't allow separation and produces minimum shear it's virtually unbeatable for a door-slammer.
PS,the beauty of the 1936 Chevrolet shown is that it is a body-on -frame construction.One can unbolt it and discard it,replacing it with a Jaray or K-Form body, cutting it's drag in half.More with the pumpkin seed.
