1984 Dodge D50 Clutch Question

My brother has a D50 Dodge which is showing every sign of needing a clutch. My brother wants to try and replace it himself. Can someone briefly describe the process and give an idea of the difficulty of this job for this particular vehicle? I would like to advise him but, the only one I have done was on a 55 Ford F150 and it was a piece of cake. However, I know cars and trucks are a lot more complicated these days.

Also, any other tips, such as where is the best place to buy the clutch or advice regarding installation would also be appreciated.
