Hello Hambers more knowledgeable than me. The question is: What is the closest roof line to the 1937 Lincoln Zephyr. I imagine a Ford of a similar year share similar shape. The 1936 and 1937 ford coupe has the same side stamp line, but doesn't flow out the back like the zephyr. The 1935 tends to have a smaller line stamp. Can you guys come up with more?
If you mean the 3w Coupe the roofline of 1937,38 and 39 are the same only front differ, good luck. /Jocke
