    Hello everyone, I'm looking for one set, a single piston ring set, new or used. This is for a history project for my son so I'm hoping some one here may have some from an previous engine overhaul or may be able to point me in the right direction
    1962 250 gt 73mm

    Thanks in advance
    Daniel

    Daniel, if this is for a history project, won't any ring set work? Just stop by a machine shop :)

    I mean who is going to know what it is from, and are they going to measure?

    Regards, Alberto

    you're right, no one would know the difference.
    My son would, he would not present something that was not accurate.
    He said the same era 77mm would work also. Apparently late 62 was introduced 77mm.

    The bore increased from the 73mm of the 3.0 litre 250 engine to 77mm for the 3.3 litre 275 engine in 1964, both with a stroke of 58.8mm.
