I am posting this info for Custom_Shelby... Steve, the pics are of a 57 plate and the one on my car. I found one like mine on eBay. I have a Custom horn button as opposed to a Custom 300/ horn ring but the parts are the same I think.

Lynn...off topic, but you need to check the "for sale" section for the paint dividers if you're still looking. pm sent
Thanks Lynn, I think you probably got the email I just sent.
This is the correct contact pin (I am pretty sure). Just found it.
