1994 Chevy S-10 clutch problems

I have a 1994 s10, it's a year change and new body change. It takes alot of 93 parts. I have replaced motor, starter, cap, wires, pluggs, clutch master cylinder, slave cylinder, clutch kit, exhaust etc. I cluldnt get the slave cylinder to bleed( went through two slave cylinders) Once I finally did, my through out bearing is now whining. I can't find out what clutch to buy? I originaly purchased one for a 1994, 94-95 take the same clutch. I think it may take a 93. But yet they both have the same discription(11;spline 1-1/8 teeth, 10 release bearing) My question to whom ever is: whats the difference between the two different year call outs for clutch kits? And how do I know which one to purchase? Ive been working on it for a year now and have never got to drive it, Have invested way to much to turn back or sell it.
