Has anyone out there had to have their trunk floor and inner wheel houses' replaced ?
I bought a mildly ruff 68 ss 396. The car has apparently had the whole rear quarter panels replaced at one time (accually a nice job too) but when ever this work was done they saw fit to braze sheet steel to the inner inner fenders and the trunk floor.

beatup68396, Those parts are available to replace those in the car, the trunk I believe comes as one piece and the inner inner fenders are also available. You might try Ausley's or Year One.
