Rumble inner curved panel screw location

[Garychinook]

Howdy,
I'm looking to locate the holes on the front edge of the rumble inner curved panel on a 31 as my new floor panels have no holes. I need the location of the four holes that are inbetween the seat stops. Maybe the linear dimension from one side. I could fudge it with some of pics here and though that isn't my way.

Thanks__________ this forum is a terrific,

Gary
