1976 charcoal canister hose routing to carter 0- 2543 carburetor

I currently have a single barrel carb on the car and want to convert to the 2 barrel super six arrangement . the existing carb has provision for the carb bowl vent line from the canister that connects to the top of the carb. The replacement carb ( carter o- 2543 doesnt have that provision)

the purge line from the canister connects to the center of the existing carb.
the replacement one does have this .

how can get these two lines connected so that the replacement carburetor will work with the existing canister . plse help
