79-80 Macho blackout

I am looking for the measurements for the black on a 79 -80 macho on the bed. I need to know how far from the front of the bed back. How far below the body line. how it comes up in the back to go around the tail light. Any measurements or pictures off a original truck would be great. Thanks, JOE.

Try machopowerwagon.com there's many detailed pics over there.

I will be doing my black on my 80 yellow macho pw at some point soon...
