This looks like the correct one from a 105 series. It uses a two hole fixing instead of the typical four and the connection point on the cylinder is different too, so more of the parts down the brakes line will be needed. But at that price, it's worth investigating and will definitely be the route I go when my brakes start acting up. If you get one of these to work, you'd never have to worry about them again.
