Another great winter project, I am having the seats re-upholstered, but I want to have the 2 structures for the front seats redone. Preferrably by myself. I know that leaning on the drivers side it flexes in a big way. I am sure the original wood is rotted out. The fronts are the only ones that need it, and of course they are rounded in the back and I am wondering how to get that roundness. I was thinking that I should use 1/8" type ply and laminate it myself, but if there is another way, I would love to hear it.
