Hi Doug,
I am new on here, but through a prior search for C6 corvette spindles for my project I found the link to your .stp files. I am currently using them in a model of my 1968 Oldsmobile 442 modified chassis I plan to build after modeling it. How do you go about setting the camber/toe/caster in the suspension in the CAD model? Do you use the planes on the spindle or the hub? I am interested as I plan to actually set this on my project today as of right now they are just placed in the respective locations. I know it isn't a gt40, but in the future I plan to build one or a similar car.
