clutch kit

Looking to install a clutch. 97 4.3 nv3500 manual transfer case. Have no clue as to what I'm doing. Any help would be cool. Thanks.

So I scored this clean 91 single cab with 140,000 miles, straight body not a spec of rust for 500 bucks on monday, when i got it I was informed that i had a shift fork issue so I could only get 1st 3rd 5th and reverse gears... Its a 2.5 with a t5... Anyway today while out to pull a part it...
