I'd try the spring first, and maybe reversing the collar. If the
wear isn't bad, it may last a long time. (note: to reverse the collar you
have to take apart the mainshaft, at least partially.)
If it's worn dogs, then the only solution might be to replace the
gear (or maybe a machine shop might be able to machine them straight again,
though there'd be slop, so I don't know if it would be any better).
The problem _seems_ to be they wear at an angle, especially
once they pop a few times, so under load they want to move apart (pop).
It might also be lose bearings allowing the gear to wobble - I was a
starving college student at the time, and this car was a major beater. (At
times I called it the sprite of many colors. Or maybe the sprite of bondo
would have been a better name. Or the sprite that ran on oil (100
miles/qt). Also I had other sprites I could fix and drive instead.
Of course, if one's gone to the trouble of pulling the gearbox,
one might want to at least hit the easy wear items (baulk rings, some
bearings, etc) plus any other possible causes (3rd/4th bearings, reverse
collar, etc). Ah, having an income and shipwright's disease.... :-( :-)
