That's helpful. Have you calculated the amount needed to tuck the wheels in enough to clear The Template line? If it's 2-4" you may be able to achieve that with the wheel offset. Otherwise, you'd need a narrower axle. Consult Suspension Measurements for examples. From there:

Rear Axle Measurements
MEASURED ACROSS WHEEL MOUNTING SURFACE

56 1/2" 71-77 Ford Maverick 8",

57" 71-74 V-8 Mavericks 8", All '75-77 6's & 8's Maverick 5 Lug 8", 49-51 Ford, 57-59 Ford 9"

57 1/4" 64 1/2 - 65 Mustang

...

59" 68-83 Corvette

60" 55-64 Chevy Car, 67-69 Camaro, 64-67 Chevelle, 68-74 Nova, 71-73 Mustang/Cougar, 84-95 Corvette

The Model A frame is 40" wide at the rear crossmember, so that could be used. But a traverse spring requires a torque tube or ladder as in the pic you attached on the left. Consider a 4-bar Watts Linkage and coil-over set-up instead. This is in a Chevy S-10:
