Hydraulic clutch fundamentals

Being I'm currently working on a truck, though I was thinking of going aftermarket because all I have heard about the stock later 80s hyd system hasn't been good.... does anyone here have any real world exp with the stock type hydraulics?
Another thing is, most I've seen with a hydraulic clutch use a diaphragm pressure plate. All I could find for my application even in an 87 that shows hydraulic actuation as std equipment is a 3 finger conventional pressure plate. Will this cause any issues? Thats one thing I hate about computer driven application guides. Back in the day I could flip a real paper catalog to the "buyers guide" and see specs of the various PNs of whatever part I was wanting, compare numbers and decide if an alternate would work much easier.
My app is a /6 D150 with an 833 OD. (would like to run something like a T5 but I have what I have and thats what Im gonna run) Far from a race truck, though I have made some upgrades to my particular engine. gonna use as a 3 season daily driver, camping rig, occasionally pull a small utility trailer short distances (~30 miles at a time 1-2x a week) with a few mowers loaded on it....
