Gary,
Both these distributors are for early Spitfires. Both have a mechanical tach
drive installed in the shaft housing. The 200 is taller than the 204.
Both where equipped with a vacuum advance rather than the later vacuum retard
unit. They are interchangeable, although I think there is a different
pertronix unit for each of them.
Any pertronix reseller should be able to tell you which kit is needed for
either one.
The Pertronix kit is a direct replacement for points and no modification to the
Distributor is required.
Cheers,
Joe
