MG MGB GT V8 Factory Originals Technical - gas cap

I removed the fuel vapor recovery system from my car 77B and pluged the vent line. Now I need a vented gas cap. Well, finding one locally hasn't been successful. The technical specialist at Moss said I needed to change the tube to the earlier style designed for a vented cap. I'm sure I've read on one of the treads here that other MGB V8 enthusiasts have converted to a vented cap system. Is there a vented cap available that will fit the 1977 filler tube?
Thanks
RIck

Rick, drill a hole in the flap inside of the filler neck, and another hole in the side of the vent tube just outside of the car. I'm e-mailing you two pics of what I did.

Justin,

I only drilled the hole in the gas cap. Seems to do the job.

The vented gas cap has a spring-loaded valve to prevent fuel escaping in the event of a roll-over. Holes in the neck inside the boot would result in trapped fumes and an explosion hazard, I would have thought. There is nothing to be gained by removing the canister and vent lines unless you are unable to have a purge line from the engine breathing system, and even then there is no real harm done.

Justin,
Thanks for the photos. That will do the trick. Carl, Paul, and ichael thanks for the comments. I removed mine to clean up the engime comparment. I move the washer bottle into the space the canister once occupied. Now it is less cluttered and there is more space.
