[Healeys] 2 28% OD questions

[Bert Van Brande]

The 28% Overdrive of the BN2 gearbox I sourced, has suffered the 'Shattered Unidirectional Clutch syndrome'.   As a result the steel ring in the annulus has 3 hairline cracks where it is held in place by 3 'rivets'.  It seems to me that the rivets were creating a weak spot and were maybe ommitted later for this reason.  I sourced a replacement steel ring, without the grooves for the rivets.  I believe this later ring is a press fit, probably facilitated by cooling the ring and heating the annulus. Is this correct?

The 3 28% planetary gears show some black discoloration and small pitting, nothing major but just feel-able with fingernail.  (The ring gear of the annulus doesn't seem to have this issue)  Do I replace these or should I not bother too much with this?  I can put pix online if this could help assessment.  If you have a spare/used set lying around let me know.  Thanks for your help.
