58ish Fairlane tail light- got one u can measure?

[idrivejunk]

Wanting to make a digital rendering and while I can use license plates for a size reference, I would like something more accurate. Don't know of one I can go look at. Got one? No rush and no big deal, just thought I might get lucky. Its the two ovals with square backup light between and chrome all around. Outer oval section on quarter, reverse and inner oval on trunk lid.

If you also know if both ovals are lit, ( inner might just be reflector?) that would also be helpful. Thanks
