I have made a portable body stand for my 69 Z28 that I will soon start to restore. Does anyone know the dimensions from one mounting hole on the subframe to the other? I need to make upright supports and wondered what the dimensions are, either overall or from the center of the car out. I would think where the body mounts to the subframe would be a suitable location. Would like rear dimensions also, but not sure where everyone supports the body back there. any thoughts would be appreciated as to dimensions and ideas to support the body during restoration. Thanks
