Vehicle is a 1970 Dart.

1) Read another post that mentioned a 5/16" roll pin to disconnect the column from the box... That was going to be my first question, "Size of punch required". So unless told otherwise I will assume this is correct (sounds about right)...?

2) I'm going to replace the wiper pivot gaskets. Should I just use the valve stem seal trick, or is there something better now?

I've "tilted-back" the dashboard on many other Chrysler products, but never an A-body. On a C-body there are screws at the edges of the defrost ducts that hold the dashboard in at the top. I don't see anything like this on the Dart. Where should I look for those screws?

Thanks.
