It's all SOS with a different label, it doesn't matter which pack you get, there all the same, just the number of certain screws given the body style!
You know what a search function is and how to use it? I guess not by your comment!I have not seen C-body Interior Kits anywhere, but I can advise you to use regular car screws and tuning screws. It will of course be a hassle to search and find something that fits.
