73' B3 340 Duster pro touring build

After consulting with several (professional's) and seeing pics on line of cars on rotisseries for floor pan replacement(with minimal bracing) I simply took 4 jack stands under the main suspension support frame areas, got the car perfectly level, took measurements at various locations and installed the "free" door braces included in my recent rotisserie purchase and had at it. nothing too complicated or over engineered, kinda like a K.I.S.S report in the Air Force" Keep It Simple Stupid is the motto I followed here. not being a convertible I wasn't too worried about twisting, flexing or bending ,all measurements were exactly the same after installation.
