Your experience with the cannisters is typical, and I don't think there will be 
any harm in simply removing both of them. They have probably been non 
functional for 20 years. You DO need to provide a vent for the gas tank, 
though. The tube that went from the tank to the fender cannister should be 
replaced with something that runs to the rubber plug at the LF corner of the 
gas tank. Take that plug out and nip off the tip of the cone; that will leave a 
hole thru it, forming a grommet. Your replacement tube should run thru that 
grommet and about 4" down from there.

If you can find some kind of plastic tube that doesn't mind gasoline that would 
be ideal. The steel lines rust up inside and get plugged.

Note that once you've done this you risk having the tank overflow onto the 
ground. I make a habit of not filling up the tank and then parking the car. The 
gas comes out of the underground storage where it is cold and then expands in 
the gas tank on a warm day.
