69 fastback trunk floor width?

[Kody]

Hey guys,

I’m trying to figure out what all the factory trunk floor/body measurements are for my 69 fastback. The car was a pro-street car with tin floors and trunk so I have no factory measurements to go off of for the new quarters. And the car is going to have a full tube chassis built for it so I don’t feel dropping the money for a trunk pan to get it back to factory specs.

Does anybody have, or can get the width outside to outside of the rear corners of the quarters?

Any help will be greatly appreciated!
Thanks
Kody
