Well clutch was slipping so changed it no joy changed slave cylindar and still slipping changing the master now as thats all of it changed. if that doesnt work any ideas to how to stop clutch slipping

stick shifts are my love. for over 50 years,
ok if the slave cycl released 100% does it? ( look and see it fully retracted)
the clutch is bad if it slips. (linkage /slave good)
no matter what car it is.
that is right warm clutches slip more hot.
a physics thing. (disk surfaces)
here is what can be bad. (all)
bad throw out bearing actual or it sticks from worn out pinon surfaces.
bad PP bad pressure plate, spring weak.
bad DISK , worn thin it hits brass rivets and SLIPS
oil on disk from bad seal front end of tranny
front of tranny pinion shaft a wreck, galled and rusted. and makes the throwout bearing stick and not release.
(all the above is moot, if slave is ok, and master cyc.
moot in the the transmission is now pulled and all above is discovered. and in truth all is just changed out 3 part klt.
done many even 4wd a 10 hour job on those.
first one done was 1964. by me and before that motorcycles and after too.
hint #2 (other) on manual linkage , no slave
the clutch free play must be kept to spec or 1/2" or clutch will slip ignored say for years.

if you gave some indication of the problem of the clutch maybe we could help
was the clutch master cylinder replaced because that is one of the main reasons clutch will slip

check /replace clutch cable or replace master cylinder. If the clutch has not been replaced it may need a clutch kit as the indications are that the pressure plate is weak ( worn clutch plate or from overheated clutch)

Explain this in some detail
You need a helper to bleed anything
My wife and I, have been bleeding brakes for 35 years, with no issues
I owned a trans shop once, and my employees did a few clutch master and slaves!

If the clutch was not slipping before that happened, chances are pretty good that it's OK.
If the master is full then it may be internally bypassing If empty or low, check for leaks at the back of the master, the line to the slave unit and the slave itself. If there are no signs of leaking or seepage check all the mechanical linkage to make sure nothing broke.

hi considering age of car and that you have no leaks on hydraulics? may i suggest you try bleeding the clutch to rid of old fluid a couple of pumps may be suffice ? b/fluid does absorb moisture and heat over time hence recommendation tat fluid be changed at period specified in handbooks ie 12 monthly ?

I am totally unfamiliar with the particular setup you have, however I know a bit about clutches, Sifting through what you said, it appears that your clutch is set up too tight. By this I mean that the throwout bearing is always pressing on the release diaphram (or fingers) on the clutch cover. As you drive this is causing the clutch disc to overheat and slip. The repeated bleeding you are doing likely has no effect on this other than that the time you spend bleeding is allowing the clutch assembly to cool off. If the slave cylinder is part of the throwout bearing and is inside the bellhousing you need to remove it and get one that is slightly shorter. If the slave is mounted on the bellhousing and activates a clutch fork that moves the bearing you will need to find a means of backing off the slave adjustment so there is a bit of freeplay between it and the fork. likely since you can drive it you are looking at 1/4" or less play to get it right. My only concern would be that you may have overcentered the fingers on the pressure plate and damaged the return spring. slipping the clutch also has not done good things to the disc either. (like driving down the road with your foot on the brake is not good for brake pads)
Good luck with your project !!

when you say you've lost resistance does the pedal stay to the floor or does it spring back up?

There has to be a bleeder there unless someone broke it off. If so, your best option is to replace it. In order to be malfunctioning, there has to be a reason. Air just does not enter the system by itself... Either the clutch master, slave cyl or a line between the two is bad, or the clutch itself is worn. Check everything carefully before deciding upon a repair plan.

Your pressure plate is going out.
