If your 70 is a leaf spring rear the convert it.If it is a coil spring rear then the frame is different. You are welder you can take the blazer frame and the 70 frame and make one.To use the 85 requires a body lift and moving spring mounts to center the wheels this would be the harder route.You can do a search as this has been covered many times.
