Can someone help with an F-150 Measurement?

[2.2 Straight six]

i'm looking into spotlight bars for the front and roof of my potential F-150 SuperCrew, i alo want a flashing light bar for the roof, but i need to know the width of the roof.

So, is there someone on here that can help me out by measuring the width of the roof? i've seen that the truck is 78.4" wide, but the roof will be narrower.

This is for the 10th gen F-150, 1997-2003

Thanks in Advance,
Chris.
