Triumph Repair: TR-6 slave cylinder extention, triumph tr 6, slave cylinder

Question
Sir
I have a 1971 Triumph TR-6 that never had a correct operating clutch. I have rebuilt the  clutch and slave cylinder, and when that didn't work I purchased and replace the master and slave cylinder. The problem is, the slave cylinder push rod doesn't appear to extend fully to engage the clutch. To remedy that problem I put the push rod in the TOP hole of the lever that actuates the fork for the throw out bearing. Doing that makes the clutch pedal very tricky. My question is, can I replace and modify the unit with a stock car clutch and slave, doing this I need to know how far the throw is for the slave pushrod. If my master and slave cylinder is working properly how far will the pushrod extend? This problem has been persistent for many years and I'm coming to the end of me, as now I'm looking for a different system to extend the rod.
CAN YOU HELP?
Thanks for any assistance that you can give me

Answer
Well Mark, I had a friend with a CHEVY S 10 that was doing the same sort of thing. we extended the push rod by making a few different length slip on ends that went into the slave and the rod slipped into. it sort of worked but the pressure just pushed the slave piston back anyway. i assume you blead the air out like you do with brakes ? and do you have a book on the car ? if so i'm thinking the gizmo that holds the throw out bearing might be worn out. it dosen't take much slak to goof it up. the bearing holder has a bolt that holds it on the rod. it can wear there and make the bearing not go far enough also the bushings there at each side of the trans can be worn, and also the middle hole it self could be oblonged and the hole in the peddal lever. it can all add up. back at the push length if i remember on the one i had it seemed to be about 1/2 inch. if i was looking at what you are doing i would take the transmission out and try to get to the bottom of it once and for all.
