mine was for the DB500 so only the one . I bought it from Phil Pearson along with a crank and many other rebuild parts . He gave me advice as to fitting . Heat up the old cylinder and push it 10mm out . Cut off the top of the cylinder and push it out from the top out the bottom . This is because it is thicker metal at the top end as the bottom is tapered . Reheat the alloy cylinder and press in the cold , not frozen , liner . Keep the pressure on till everything has cooled down . This is because you can get back creep of the cylinder until it is cool . As for fit it was quite a tight fit and did need a press to fit it . All went great needed boring to the supplied piston and has ron perfect ever since .
