Cargo Light on a 67?????

[passthebuck]

Hey all!

Now I know that the "where do I install the cargo light" question has been asked a thousand times, but this is a bit different... I'm planning to put a cargo light on my 67 & all the measurements are for the larger windowed 68-72 trucks, & I have a small window truck....

What are the measurements / placement fror a cargo light on a 67?

I've searched & nothing 67/small window related comes up.

I'm hoping someone has a solution to this...

Mabe instead of measuring from the window, I need measuirements down from the seam at the back of the cab?

Thanks in advance for your assistance!
