This is an extremely well made set of points, condenser, and terminal block. They are preassembled for ease of installation, so you don't need to know how the insulators, wires, and spring need to be assembled to prevent failure/shorting. This is the same assembly available as a full breaker plate package.
They fit all 22D (TR6 and Jaguar), 23D (Mini Cooper S), and 25D distributors (British 4, 6 cylinder cars from '62-74.) They also fit in the DM2 distributors, but the terminal block will not fit properly unless the entire 25D breaker plate is installed.
