Hello i just replaced my clutch master cylinder and the slave cylinder i bleed the lines but i cant get the truck in gear what can i do

Have someone operate the clutch pedal several times while you watch the clutch arm that is connected to the slave. It should move back and forth. Manually check for free play at this arm--it probably should be about 1/4 inch or so. Is the slave body attached firmly to the transmission or bell housing? Fit a pry bar into the space around the clutch arm to prevent movement and test the clutch pedal for 'spongy' action--this would be air still in the system. Any missing springs around the slave? Put the truck in gear, push in the clutch--you should be able to move the truck without turning the engine. Don't try to drive until this operation works.

You have a loop in the system below very difficult to bleed you may have to reverse bleed with pheonix injector or remove the slave and hold above the loop in the line then push in the slave while hold finger over the slightly opened bleeder screw you will find very messy you can try this way with out reverse bleed pheonix inject hand held pump nissans and some odd english jeep systems can woop your **** getting it bleed . good luck !

Did your clutch work ok before you replaced it ? if so recheck the clutch action at the tranny it should move 5-6 inchs when you depress it if not rebleed it ?clutch fork should move if not you still got air in it ?
