Projects measurement needed. 28-29 roadster

I am piecing together a roadster and I need the width of the panel above trunk please. From seat to trunk. 30-31 panel is shorter and I can't mock up my quarters and deck lid correctly. Thanx, Ron

 

@ the bustle T strip -- T strip 371/2"
@ the trunk opening T strip -- T strip 365/8"

Thank you Walter. Could you measure front edge to rear edge plz? From seat back area to decklid edge. Thanx

 

Are you talking about this panel?

Its 11 1/2'' from the front edge to the rear edge.
