Looking for thread on narrowed Advanced Design bench seat for Highboy

I've been through the Tech Archives and searched and can't find this old post.

Someone once posted a good article on narrowing and lowering the bench seat out of an Advanced Design pickup for use in a Model-A or Deuce.

Help me out if you can find the post, or have the pics, or originally wrote it, or ...
