That air cleaner comes with a nipple to put on the base. It is actually for the crankcase evaporative system, but you could use it for the canister. If you really want it right, you could get a second nipple and use it for the canister with the original for the crankcase evap.
It would not hurt a thing in the world to run a tee from the ported vacuum port to both the distributor and canister. You may need to readjust your vacuum advance, but that's very simple.
