Have a 73 240z clutch is giving me a hard time. Master cylinder in good shape, replaced slave and flushed out system, but clutch still isnt doing anything. Any ideas on how to fix this without having to drop transmission?

What do you mean by "the clutch still isn't doing anything"? This is a little too vague to be of any use in diagnosing the problem.

slave cylinder is all the way out but is just sitting on fork.

transmission is down, is a brand new clutch. lengths for rods are perfect. Not sure why wont disengage.

Make sure you bleed the master and then the slave. Did you put the clutch and tranny in? It could also be that the fork is not on the pivot.

master and slave were bled. Fluid running through. Possible master dried out?

no clutch seems to be replaced before i got the car, but very recent. seems to be original tranny. Gears run fine from what i could do without a clutch.

Fork seems to be fine. Going to lift tranny back in once done with floor pans.

So the PO put the clutch in? And it worked after you got it?
If you watch the fork movement when the pedal is depressed does it have sufficient travel?

SwitchAZ

When pedal is pushed i get nothing. The slave bar is all the way out and so wont give the fork any movement. Fluid is getting to slave, it has to be the length of the bar or something with the fork angle im guessing? im not sure. everything is reading out that it should work just fine.

Who put the clutch in? Who put the tranny in? Who bled the lines?

SwitchAZ

clutch was previous owner, so was most likely last to remount tranny. Is correct clutch. i bled lines, and will be remounting clutch again personally. only thing missing in bell housing is the fork boot.

It's the throwout bearing collar, it's from a ZX & it's too short so the bearing's not pressing on the clutch fingers even when the pedal is fully depressed. You may need to drop the trans agin to verify clearance & travel of the the release fork & bearing/collar assy. It sucks. Good luck
