<DIV><FONT size=2>According to Clausager there were four different sets of
columns and wheels over the years and they are not interchangeable. But
that isn't necessarily borne out by the Parts Catalogue, and North America may
have changed from the first to the second type with the Mk2, whereas the rest of
the world didn't change until the 1970 model year, and only had three
types. The last change for the 1977 model year on only has an impact on
indicator cancelling and horn push, the splines don't seem to have changed after
1970. Incidentally the horn push moved to a column stalk for just one
year before moving back to the wheel, what impact that had on the wheel centre I
don't know.</FONT></DIV>

<DIV><FONT size=2>For North America the splines for the Mk1 were
3/4" x 48, then 5/8" x 36, then 11/16" x 36. If that wasn't complicated
enough there were three different thread and TPI combinations - Mk1 11/16"
x 27TPI, up to 1970 9/16" x 27TPI, then 9/16" x 18TPI. </FONT></DIV>
