Yes, there should be a copper bellows in the frame there. Do you have 
the thin rod coming down from above with the threaded end?

Check the vacuum advance by putting a small hose on the fitting and 
sucking on it while you watch the timing with a timing light. If it 
doesn't do anything you will notice that when you suck there is no 
change. You can also see this with the engine off; no motion when you 
suck. A good vac adv mech is sealed, so if you keep getting air the 
diaphram is broken and muxt be replaced. If this is your only problem 
you can buy a replacement diaphram and install it yourself. You will 
have to remove the dist to do this, but that is not hard. You will 
have to put it back when you are done and that requires a timing 
light.

If you are worried about any of this I will rebuild it for $55 plus 
major parts. If it were mine I would do a complete rebuild because 
they all pretty much need it by now. There are some things that can 
get cleaned up which may prevent future problems.
