Note that this kit is not offered as being suitable for the various reproduction cylinders which are on offer elsewhere. 750 & 101 Series Rear Wheel Cylinders - There are two sizes of rear wheel cylinders fitted to Giuliettas, 101 series Giulias and very early 105 series Giulias. They look the same externally but are of different diameters, 0.7" (17.8mm), or 7/8" (22.3mm). Generally, the larger 7/8" cylinders were fitted to cars with drum type front brakes, and 0.7" cylinders were fitted to cars with disc type front brakes. A number of cars are being found with the wrong cylinders, and even some with different size cylinders on each side! So it is worth checking both your cylinders before ordering a repair kit or a new cylinder.
