  (inner diameter) x (outer diameter) x (length)

The BK15x24x26 supercedes the C18x24x16.

To me this means the input shaft of the post-88 Audi 200 was thinner
than
the older ones. Is this correct? If I am measuring 18mm diameter than I
should be using C18x24x16, right?

Anyone know difference in shaft diameters?

The bushing on the type-44 automatic's crank was a 15mm inner diameter.

Should I try and find out if there is such a thing as a 18x24x26?
