'74 Duster Floor pans

What's the damage like? Does it just need 1 or 2 floor patch panels or the whole thing?

You can get separate Goodmark panels for fairly cheap but they require some massaging to fit right. AMD stuff requires very little extra work. Basically cut and weld. So you have to decide what's more important to you, time or money? Also it depends on how much of a stickler you are about the restoration. Patch panels are more obvious once installed but most guys aren't too worried about that since it'll be under carpet.

Search whole floor replacements on here. Most guys will brace the car with 2x4's or something like that to keep the car from tweaking since the floor is a big part of the structure.
