How to replace clutch pressure plate and throwout bearing
I'll tell you like I tell everyone else, go to the local auto parts store, spend $25 on the repair manual for your truck and in the manual is a step by step procedure for replacing the clutch, P plate and bearing. This all entails removing the transmission. And a 1989 has a hydraulic clutch,and the slave cylinder is internal if I'm not mistaken, so why you have the trans removed you should also replace the slave cylinder because it'll be just your luck after you get it all back together the slave starts to leak.

The vehicle must be raised on four jackstands. Disconnect the battery pos(+) terminal.The driveshaft has to be removed . Then remove the three starter mounting bolts, this will allow acess to the main feed wire to the starter, remove the 1/2 inch nut and lock washer and remove the wire.Place the starter to the side. Next you'll need to remove the rear tranny mounting bolt. Then remove the crossmember from the frame. This is where you'll wish you hadn't started this job. You must support the tranny while sliding the crossmember out. This can easily be accomplished by placing a small floorjack centered under the tranny pan with a 1 foot by 1 foot square piece of plywood on the jack lift cradle.Next you'll want to remove and put aside any sensors (back-up, speed, gear position...) if utililized from the tranny. Remove all bell housing bolts. remove the slave unit from the bell housing. Very carefully roll the tranny back a small amount and lower the jack a small amount. Continue this until the tranny is free of the pilot bearing.Lower and remove the tranny. Remove the pressure plate in a rotation motion as not to put too much strain on any one single bolt. Remove the pressure plate being careful not to be hit by the clutch disk which will now be free. Check the condition of the flywheel for cracks and glazing. This will determine if it needs to be turned or replaced. Check the pilot bushing with your finger to make sure it turns smoothly and freely.Then......put it back together with your new parts. Any questions? Good luck, Dana

It is very difficult for you to disengage the clutch by hand or with any leverage you can get outside the transmission. There is over 200 lbs of force clamping on the clutch disc.
If you replaced the clutch and took the slave cylinder out of the transmission without putting a brick under the clutch pedal or disconnecting the pivot arm from the pedal then you ruined the hydraulics. Buy a new PRE-BLED system from a local auto store. Generally this is the problem.
Either that or the clutch fork is bent or you installed the throwout bearing backwards (or simply fell off the fork which is not all that uncommon).

It is a fairly easy job for any person to tackle providing they can handle tools, (some people can't turn a screwdriver), First you have to get the car up in the air with room to move under there, put it on jack stands if you can, but definitely on something so that when it comes down it doesn't squish your legs or your head. Pull the transmission, This will probably include the cross members and exhaust mounts, linkage, tranny mounts, drive shaft, could be a bunch of stuff in the way, once it is on the floor, you can remove the pressure plate off the back of the engine, pull off the clutch plate, note the condition of the flywheel, if it looks like dried mud, it needs to be surfaced. A burned flywheel will cause chatter, get the new clutch plate on there, first make sure it fits the tranny, real important, better to check now than when you are wrestling the tranny back in and it doesn't go because it is the wrong clutch spline, line up the clutch with the pinion bearing, it should slide right in nicely. Get the throw out bearing set before it goes back in, bolt it back together, you should be burning rubber and pulling wheelies again in no time. You might have to adjust the clutch slave cylinder pin if it has one, get more throw out of it. Or less. You might find some videos on youtube just for your car, but they are basically all the same.
