This is an excerpt from the 49-59 Parts Catalogue.

If you don't have a copy of the books, there are copies everywhere of them on disk. I got a copy from Dan Jessup (a member on this site) and downloaded them in PDF form from Dave ( one of the moderators on the square bird forum).
A must have resource for working on our cars with exploded views of almost everything.
