I'm often asked "where is there room to carry all this stuff?"
You have to be creative. I have two Healeys so I keep it all in a soft sided lunch bag that was a give away item. That way it can go from car to car.
Marion Brantley uses a Tupperware pie holder. Painted flat black it is the perfect size to fit under the spare tire. I have seen spare fuel pumps under the battery, hoses and belts behind the cover for the fuel filler pipe (attach the cover with Velcro for fast removal). Don't carry a tub of wheel bearing grease, just put enough in a zip lock bag to get the job done. Correctly done you can open the trunk on a Healey and never know all those items are in there.
So often we travel in groups to Healey Events. Don't carry spares just for yourself, think of other Healey owners you may travel with who may need one of your parts, we all have to work together.
