Dizzy Question

["James Henningsen" <trguy@cfl.rr.com>]

Hello Listers!

Happy Post Thanksgiving.  I have an early 6 cylinder motor (CC 902 E) with
the early Lucas dizzy (retard and vacuum advance) model 22d with this number
on the housing (41202A).  I have a late model 22D - number on housing
(41352B).  Can you swap the early dizzy with a later model one?  Or were
there specific dizzies for specific year motors.

Thanks,
Jim Henningsen
