Thanks to you all. I have no risers. Am starting to wonder what else is missing. Wher can I get a good copy of a chassis manual and an interiot manual that would have detailed diagrams?

So should the car have a one piece long floorboard on each side? I have a short piece from the front of the seat to the firewall and a longer piece from that to the back seat (convertible). Is that OK?

 

The factory service manual available from most all mustang parts places for about $40 should be on every classic owners bookshelf. It will show you exactly what should be there. For a free bee, download the NPD catalogue, it has good diagrams of most of the parts. It sounds like someone has been after your car with a cut off wheel! By the way, the seat platforms act as a stiffening element to help the unibody carry some of the torque. You really should have something to brace the body between the side rails and the transmission tunnel.

 

Thanks very much! What is the NPD catalogue?

 

OK, I was wrong. I have them. I need to remove the carpet (new) to see what the floorpan looks like, rust-wise. There is a hole I can see from underneath the car that's about the size of my fist, but I'm assuming I can patch that. What's the preferred method of keeping rust at a minimum? Is there a spray or brush-on chemical treatment that works?

 

por15 is a popular choice, it is a rust encapsulating product,

but a fist sized hole in the floorpan needs to be patched, not just have a rust stopping agent applied.
