Try to be more specific like Vacuum wiper system, engine vacuum system or fording vent system. As Brian says you already have the lengths of each tube in your ORD 9 SNL G-740 M38 parts list which if you do not have a paper copy you can download the PDF copy here for free.

There you go, that edit makes it obvious what you are looking for!

See Hal's answer below. If you use the many new crate engine photos in my album you'll get darn close. http://www.willysmjeeps.com/v2/modules.php?set_albumName=album131&op=modload&name=gallery&file=index&include=view_album.php

I need the dimentions of the bends from the vac pump to the manifold and from the vac pump to the ws wiper/distributor connection.I have the tubing and I need the correct dimentions for the bends so they fit correctly as if the bends are in the wrong places it will not fit properly.

The best way to do this is connect one end loosely and bend to fit...
