You really can't do a 72 statically. It is an inherently dynamic adjustment. 
The only manual that explains the right way to do it is the Bentley. The 
timing light also allows you to easily check the mechanical and vacuum 
advances, both of which are crucial for proper operation of your 72.  

Check Sears, NAPA, or eBay for a timing light. I love my Sears. It has been 
a great investment. I strongly recommend the inductive pickup kind.  

It is possible that you could do a proper dynamic adjustment then see where 
it is timed statically. After that you could time it statically to that same 
place. I would not trust a shop to do it correctly since this is a one-year 
process. Borrow a timing light and do it carefully yourself.  

Yes, the first time you do this you'll be bewildered and spend the better part  
of an afternoon, but you'll learn a lot and come out of it a lot better off.
