Has anyone installed a Quicktime scatter shield on an E-body? I am in the process of installing the shield, but the stock torque shaft ball stud doesn't fit on the bracket located on shield (the hole is too small). I don't want to drill out the bracket if there is another ball you can use. Additionally, if I had to drill out the bracket not sure which hole to enlarge. I called Quicktime and didn't get any good information. Also, I was curious if you can use the stock Z bar. I appreciate the help!
