Looks like you saved some money on brake clean. I’m guessing you didn’t replace the transmission input seal based on the oil I see dripping off the input shaft. Any time I have a transmission out, I replace the shaft seal and clean the bellhousing so that you could eat off it.
Now, on to your problem. Did you install the clutch disk backwards? It sounds like the pressure plate is bottoming out. If the disc is in correctly, could the disc be against the crank to flywheel bolt heads?
Because you are using an adapter and custom flywheel, I expect you need to pull it all apart and figure out why. You can remove the flywheel and reassemble the clutch. You can operate the clutch in a press and see that eventually the disc is released. |

This issue happened to me last year! The longer pushrod in your photo looks like the correct length FTE brand.
Notice how much further the piston travels up the cylinder with the longer pushrod. This equates to the pressure plate being pressed further and the clutch being disengaged more completely.

Yeah, let us know how it turns out.. If the short one does the trick, I'd love you have the long one from you if it doesn't have a home yet.

Ah I’ll hold on to them both I think. The long one is the one I’m putting in to fix the issue. And I’ll have to get a replacement for the aforementioned sister’s van. |
Interesting, from how I understand your original condition I figured the throw was too much and the shorter shaft was going to be the solution.
FWIW, on my 83.5 I have the RMW adapter plate and flywheel and I used the same slave/pushrod that was on the there with the 1.9. it starts to release at about 1/4 pedal travel and fully releases at the carpet... Infact, if my thick floor mat makes it's way under them pedal it has a hard time fully releasing causing difficult shifting.

| Based on the original description, I don’t see how using the other rod will solve the problem. Hope I’m wrong. |

| they encountered this same problem at the shop he works at with another Vanagon, bottoming out clutch pedal, they put a longer pushrod in the slave cylinder and it fixed the issue! |
Based on the above text, the pedal was bottoming out (I assume the clutch was not disengaged yet), and the longer rod fixed it.
The OP has the opposite issue if I read him correctly.

When I depress the clutch pedal it hard stops an inch and a half above the floor. When I disconnect the slave cylinder from the bell housing I can fully depress the clutch so the hydraulic system seems fine. |

| Wonder what else was changed when the pushrod was changed? Was the little arm on the throwout shaft changed or was it something else? Maybe the bracket for the slave cylinder? |

With the shorter pushrod and the aftermarket release bearing, disk and pressure plate, the piston in the slave hits the circlip before the release bearing has gone to its full travel. That is why the pedal seems to "bottom out."
Installing the longer pushrod will allow the clutch to fully release before the piston hits the circlip.

Eg. It puts the working range higher in the slave cylinder.
This is true if it hits the circlip. If it's hitting in the clutch a shorter pushrod may be the solution or the problem is something else.
Watching how this will be solved.
