Hydraulic Clutch Conversion

I am building a completely custom 78 F100 with a 5.9 Cummins mated to a ZF6 speed. I am trying to figure out the best path to connect the hydraulic clutch and eliminate the clutch linkage. The cab I have was originally an automatic, so I have to buy a set of pedals anyway. I will be using the super duty master/slave cylinder assembly, along with the super duty brake booster and brake master cylinder.

My question is which pedal assembly to use, obviously the 70s F-series pedals would be the simplest to fit into the cab, that just leaves connecting the pedal to the master cylinder, has anyone done this? I could install the set out of the 90s F-series, but those were designed with the column going over the pedal assembly, as opposed to under like the 70s trucks. Or, I could install the super duty clutch pedal, which is actually a separate assembly. Only issue I see is the master cylinder would come out somewhere under the brake booster.

I know people have done this conversion, or at least similar with the ZF5, would just like to hear what anyone else has done, and the pros/cons they have with it.

Might check to see if someone makes a kit for your swap.

I've looked at couple options, most of witch seems to be geared towards buggies or hot rods, I could probably make them work, but I'm not ready to do that yet, for a couple reason. First, I want to stick to parts that are "off-the-shelf", more or less, in case something breaks on me down the road. Custom parts can be hard to get and hard to find, and if I have learned anything from the state of the world, it's not to count on being able to find what you need, if I narrow my search, it gets even harder. Second, I know people have done this kind of swap before and I really just want to pick other people's brain. Third, I'm not stuck, I'm just at an intersection trying to decide which way to go.

And finally.......By God, I have a welder and duct tape, I'll make it work!!!

I used stock pedals and the dodge hydraulic setup. 12v but might help if you are fabbing it up


Mounts to but is Independent of firewall.

‘Test bracket’ helped determine correct pushrod mount point

Braced at dash and to pedal assy
