Here we go.
It's an involved project. Disregard those who just say it pops right in. You'll need the following:
1. Correct transmission (not the truck model) WITH the correct spine pattern for your new clutch, otherwise you'll have to source the correct input shaft and retainer.
2. New clutch disc, pressure plate. The Centerforce unit is great.
3. As mention earlier, you'll need a properly balanced flywheel.
4. Input roller bearing or bushing to drive into the crankshaft.
5. Correct size bell housing (10.5"), which comes in both car and truck applications, aluminum or steel.
6. Correct size fork pivot and fork, otherwise you'll never be able to push the pedal or the pedal won't push far enough to disengage the clutch.
7. Clutch pedal from donor car. Plus bushing and return spring.
8. Z-bar assembly (install new bushings!) and mounts or DIY hydraulic clutch kit
9. Crossmember
10. Crossmember transmission mounts
11. Shifter, correct shift linkages (there are differences between the A833 and A333 overdrive.
12. New or resized driveline
13. Speedo gear, maybe speedo cable
14. A cutting tool to cut the floor enough to allow for installation, but this isn't always necessary
Also, check out this article on modifying your clutch pedal arm. I've have to do this every time.

As you can see it's doable, but there's a learning curve. And it's obviously not just plug 'n play. I've done it a few times and I can tell you that it takes some money, time, and effort. But I also think it's well worth it.
