I have removed, with considerable difficulty, floors and inner sills from my '61 TR3A. Total rust. Now I'm ready to rebuild. But I neglected to note where the square fabric pads went. Are they on the outriggers, beneath the inner sill extension that fits to the outrigger square? Or are they on top of the inner sill extension, below the floor? Or is one pad on the frame, and the other on the sill, between it and the floor?
