Hydraulic clutch fundamentals

I could do with what I have, I believe. Might need bushings in the Z bar if I stay with mechanical linkage.

I did buy a factory-style replacement master/slave combo via Ebay. so if I go hydraulic, Im gonna try that first, and see how that works out. I do have a couple of these in used form as well, courtesy of my kid.

The guy I got all this 4 speed stuff from, got all of it as he could find it, in several junkyard trips over the years. all is marked what year it came off of, all is '81-87. seems very complete from what I remember. it's been a couple of months, since I looked at it all. I know for sure that the bellhousing I have does have the bracket on it to mount the factory slave.

He redid an 83 D150 and I think just gathered parts as gettin was good, "just in case" he needed them for his, which is a factory 4 speed truck.

I've asked this question about the hydraulic clutch idea, on a couple of forums. On one of those other forums, someone posted a pic of a factory /6 bell with the bracket for the slave on it. My bell has that bracket. But the fork that he showed, looked kinda weird. It wasn't straight, had a weird rearward curve to it. so I might need that.
Also, the clutch pedal I have (made for mechanical style linkage) looks different from what I am now seeing, has a metal strap welded to it at an angle to offset the pin to connect to the master pushrod further over towards the left. I'm sure I can fab that up, and modify what I have easy enough to match that configuration if need be.
truthfully, I need to get back into that tote and see exactly what all is present again, now that I'm getting closer.
I would like to eventually find a column for a stick equipped truck, or at least the "shift bowl" to swap out the one on my column now where the A/T shifter goes....
The one thing I will definitely need is the angle bracket the master clips into, behind the firewall. My kid pulled the one from his truck, I think between us, we can make that ourself.
The other thing I know I need, is whatever retainer clips and/or any bushings where the master would connect at the pedal.

this brings up another related question. What is difference in driveshaft length as compared to same truck with a 727? (since that's what I have in truck now)
