Need Help finding a part. Mounting bracket for 1967 Dodge Dart Convertible top cylinder pilot bracket.

The passenger side bracket of this piece is broken. This is the bracket that holds the cylinder in place while allowing it to pivot when using the convertible top. The pilot bolt broke off and is missing (Unknown location, cannot find it anywhere in the seat well). Where can I get a replacement? I cannot find it on search, and I am unaware of its exact name
