I'm new with these cars and i read these Hydroboost brakes are great so I bought them at adv auto for my 87gn. I got the master cylinder and Power Brake Booster, But what else am i gonna need ? I see all kinds of different things on here. i see 5 feet of hydrolic hose and a 3/8 TEE fitting, is that all i need? And mine didn't come with the gas pressured reservoir that I see on all yours. is that a must? please help
