HELP! My husband changed the right rear wheel cylinders on his 280Z. While he was doing it, he replaced the brake shoes. Now he can't seem to get the drum back on the back wheels. He didn't keep the old shoes but said they looked identical to the new ones - that the new ones just looked "new" and "slightly thicker". He said the drums had never been removed and were kind of tight coming off. Does anyone know what could be the problem? Is there a "trick" to putting the drums back on????
