i got a 74 260z and she always crunches in second so i think the synchros have gone and the clutch bites right near the top, prob worn our right?. well i was wondering what do i do with my gearbox, do i get synchros put in? do i rebuild? or should i just get myself a new gearbox? and if so what one should i go for that wouldnt need to much stuffing round to put in ?

Sorry, can't really help with gearbox as I don't know the going price for one. I'd say rebuild it, unless you can find a cheap one. That way you'll have a gearbox which shouldn't need pulling apart for a while, again, it depends on price and what money you have available to spend on it.

It crunched into second and started to slip with any more than half throttle.
You can actually re-use the synchros from the 3rd/4th gears and put them onto ur 1st/2nd.
this makes it easy as you can get a cheap second hand gearbox that will have worn out 1st/2nd synchros but the 3rd/4th should be fine.
While you have the gearbox out it will be worthwile checking to see what has caused your clutch to wear...
In my case it was a cracked flywheel.
It could also be a rear main seal that has dripped oil onto the pressure plate for you?

also for anyone rebuilding... the lock nut on the end of the shaft that holds alll the gears on is a one use item so it is worth buying a new one (about$12-15) when putting it all back together. The shop rebuilding my box kept using teh same nut and within a month it would undo and i would lose 5th and reverse etc...
