Transmission Rebuild Part II: A Study in NK Throw-Out Bearings

While re-installing my original tranny after its rebuild, we decided to swap the throw-out bearing. To our surprise, the correct bearing (according to REALOEM) is quite a bit different than the original one that dates from 1967, and in fact somewhat less tall.  It works fine as it seemed self-asjust in relation to the slave cylinder when the tranny was put back in the car.  Here is a pic of the three bearings - my original one on the left, the new one in the center that I am now using, and the later '02 style bearing at the right, which is used in the Series II NKs, I believe.

Fascinating how things change, for reasons that are probably now lost to history.
