Need transmission parts

[The General]

I have an STD.2 gearbox.
I need a main shaft 67-3313 (14 teeth gear and shaft all one piece).
And main shaft 3rd gear 67-3310.(22 teeth)

The chart "Internal Gearbox Ratios for A and B Group S/A Models"
shows these parts were used in trannys marked:
TRI, TRI.T, ARRT, ASC, ASC.T, STD.2

I'm in th USA, I would consider buying a whole transmission if those two parts are good.
Slight wear is OK, no chips on teeth or on interlock.

Thank you to the poster of that gear chart, greatly appreciated!

General,
              That gearbox seems to have been an American market type.
A few landed here in Oz but the consensus seems to be that it was a terrible box with the very low 1st gear.
The STD box is much more user friendly.
As a matter of interest, some of those boxes are stamped STB2.
