[Mgs] Steering Wheel

[PaulHunt73]

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.

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.

  I have a 1969 MGB GT with some aftermarket steering wheel.  Does the early (63-67) steering wheel in all the catalogs fit my car, or is the splined shaft a different size?
