This is a brand new replacement 25D4 distributor, made once again by Lucas after being unavailable for many years. It is correct for MGA, MGB, Magnette, Metropolitan, and any other BMC B-series engine of 1489, 1588, 1622 or 1800 cc. which are not equipped with emission control devices.
Back in the day, Lucas made dozens of different distributors for these cars, which had different timing advance profiles. Now they sell one distributor for all these applications, and it works great for pretty much any B-series engine from about 1955 to mid-1974. It comes complete with brand new points, condenser, premium red rotor and cap, ready to install in your car.
We also sell later style 45D4 distributors; see Related Products below.
