Headliner measurement.

[cskins]

Hello everyone,
I am looking for another measurement so I can order some fabric for my headliner.
My prout is a snowgoose 37 not the elite version circa 1986. It is in Mexico so I cant measure it myself. I need the length and width of two sections of headliner that has plywood panels behind it. The first is the starboard panel above the setee from the bulkhead that seperates the cockpit to the bulkhead separating the setee from the forward cabin. The second is the panel over the galley.
Any help would be greatly appreciated.
Thanks!
