Formula Jr. resto getting underway...

First, I'm a new member but have visited this site many times before...Thanks for all the great info. I recently bought a '67 formula jr that needs a total resto and have a question. I am unsure how the liner floor was originally fastened to the hull. My floor sits on, and is glassed to a 3/4" plywood subfloor (very much rotted) that runs the entire length and width of the hull forward of the engine compartment. I've looked at many of the Donzi "deck off resto" photos on this site and all the Donzi liner floors are cored and sit on the stringers only (or aluminum angle like G Carter) and are tabbed in a few places. Which way is correct for the jr? Thanks in advance for any light you can shed (or photos you can share or direct me to).
Regards,

These pictures show the overall needy condition and the floor as it is now...

It's nice to see you saving one ddjk. Welcome, take your time and good luck, there are a lot of folks here who can provide guidance.
