1991 Chevy S-10 clutch wont disengage, hard to get into gea

I have a 91 s10 4wd 4.3ltr. The problem i'm havin is I just got my truck back from the chevy dealership, and I had installed, new clutch kit, shift fork, pivot ball, hydraulic line, slave cylinder, and clutch master cylinder. The problem: the truck has to be in gear to start now, also when the clutch is to the floor the truck still creeps forward like the clutch is still engaged, (on flat and level surface). After a couple mins of driving it wont or is VERY hard to get into any gear. He said that it took them almost an hour to get it bled to get a clutch pedal and I know for a fact that the push rod on the clutch master is not adjustable. It also does have the bleeder on top of the slave not the bottom. So that cant be it. Also I guess I should include that the truck came as an auto and is now a 5 speed (previous owner). The truck is a 91 the slave is from a 92 and the clutch master is from a 94 with roll pin retainer fittings, not thread in type, also has the resevoir seperate with a hose running up to it. Also the hydraulic line is from a 94 if this makes any difference in the solution. Does anyone think that thay just didnt bleed it enough? Any other things that could be causing this? Thanks for any and all replies, shawn
