New clutch system components and slipping

Concentric slave cylinder was leaking. Installed a new clutch master cylinder, new slave cylinder, clutch and pressure plate. Pressure plate was not the self-adjusting type. Pedal is almost all the way out before it engages and there is still free play left on the pedal itself. It is slipping in 3rd, 4th and 5th if I give it any substantial amount of gas. The clutch master cylinder has no adjustment for the pedal and as stated, the pedal is almost completely out before engagement. Am I missing something here? Pulling what little hair I have left out!
