H55F and tcase question

[Stumper]

Here is the scenario. Bought a H55f mated to a late model, vacuum transfer case. This is all going under a 79ish FJ40. We know of the clearance issues with the tcase and the frame member of the 40. The big question is, can the vacuum actuator on the tcase be removed and the tcase made into a manual tcase vs the vacuum tcase. Is the vacuum actuator mearly a vacuum assist for the manual shifting. The other option we have is that we have a 83 FJ60 tcase that could be mated up, but run into the issue of the oil cup needing to be machined out. All of this is going to be mated to a fresh 2F. Just need to know if we can convert the tcase we already have matted to the H55F to work under a 40.
If anyone can lend some ideas or experience, please let me know.
Thanks,
Stumper

the vacuume is only for 2 wheel to 4 wheel, ie just puts it into 4x4. low/high is lever. its not an assist. Not sure about the rest, I looked into it and forgot what I learned.........

why not keep the vaccume set up? you will need some selnoids to run it but that shouldnt be a big deal. BTW 40's were offered with a vacuume shift option(up to 1984) in other markets and from my US lit it looks like it was a possible US option

You can swap the ft nose cones and vac switch assy for a direct shift assy. I "think" you can just swap the shift mech itself
