In order to make up for it, I shrank the template a bit and lowered it to put it in a sort of compromise position that you see in the image.
I did this because it would seem to me that once the air starts moving along a given taper, it would be unwise to push it back up too much, I'd think a sort of go with it idea would keep the air moving as smoothly as possible.
The black line was used as a measuring device, it appears to me that a trailer would end at 82" or so if this line were followed.
Anyway, hope this helps.

Thanks Charlie,I've been working off photos Gary sent along with a Toyota factory shot of the 2nd-gen car in true-length.
I'm working @ 28-inch image scale ( car / trailer ) and have made allowances for differences between two cars.
I will follow the 'Template' in elevation which will produce a 'notch' behind the backlight,projecting straight back atop the spoiler 'til it hits the 'line'.There's nothing I can do about the roofline,so the trailer will just have to get back to the line on its own.There will be a locked-vortex captured in this area.
In plan-view,at the very base of the trailer we have issues.For the axle/tire width,@ 52.5-inches ( outside-to-outside ) the tires fall outside the 'Template' boundary.
Chopping the pull-bar a bit helps by moving the axle forward a smidge,but it still won't fit.Sectioning the spanwise frame rails and axle would fix this.
Gary will have to make the call on this one.
Leaving the standard width will force the trailer body to go hyper-'Template',widening the body significantly to allow enclosure of the wheels.
I've been working on the drawings this A.M. and will photo-reduce and scan
/post as time permits.
Right now,as things sit,the trailer body ends @ 75 % 'Template' in elevation.
Ground clearance,with projected Toyota diffuser angle is 14.66-inches.
Trailer body height,at terminus ( with the higher resolution drawings) is 22.25-inches.This will provide some area for the license plate and lights.
The small wake area should possess the 'phantom' tail phenomena.
