I need to install a fan shroud on my 70 440 cuda so that I can get the factory air worked on. This is probably a stupid question but which bolts need to be removed to get the fan off? A B or C on the front thermal clutch? See the lettered lables on the picture below. In case its too hard to read the A arrow points left, the B arrow points right and the C arrow points up. I think I need to remove A but they all look like a bear to reinstall so I don't want to pick the wrong ones and regret it - not to mention I will have to remove others to get the job done. Any and all advice is welcomed as well as other better ways to get it done.
