I'm sure everyone is aware of this, but JIC :

There are two different detent springs, used in different locations on
different transmissions.  The part number I quoted matches Malcolm's specs,
and is used with a "bullet" shaped nose piece and a spacer under the
retaining screw.  Later transmissions used this both for 3/4 and reverse
rails, while earlier ones used it only for the reverse rail.

The other spring is larger diameter (about .360") and longer, used with only
a ball bearing to bear on the shaft.  The earlier transmissions used this
for 1/2 and 3/4, while later ones only used it on 1/2.  P/N 101236

I'm not sure when the changeover was, perhaps at the introduction of
synchromesh on first gear.
