Thank you for the clairification. I mistakenly remembered it to be an R151. I have corrected my earlier post as well.
By the way I fail to see the charm in this type of conversion. You are going to a setup that will require future maintainence and parts availablity will be dicey at best. If you are dealing with a hobby vehicle that can be taken out of service for possibly months at a time it's not an issue. If you depend on the vehicle I think it's a bad choice.

Looks like the bellhousing I need is 31111‑60300 and the flywheel is 33136‑60020 for the H151 to 1FZ. There are some trader sites on the internet that price them reasonably in dollars but I don't know if they are reputable or not. Also, anyone know of a North American source for that bell housing. The H55 is still an option too, but all things being equal I think it would be easier for me to get the one that actually came in an 80 as there would be fewer surprises.
Also would TIS have exploded "fiche" type diagrams? The one site that used to offer this is shut down. I really need to see all of the little stuff to do this. Also looking to see if this can be done in the 5-6k range dollar wise. I know it was posted earlier in the thread that was doable. People have been throwing around 2500 for good rebuilds on the auto so in comparison to that I dont see it as a massive expense. The Part Time T/C will keep me from buying new Birfs in the near future so that can add in as well. It won't pay for itself, but it is doable at that price range.

Dan - It is my daily driver BUT it is a daily drive I could make on my Schwinn - literally 1.2 miles - so it can go down for a bit if needed. Until I retire in 4 years that is the extent of my commute. I will agree that the auto makes way more sense from a financial standpoint but I am so far past that with this thing I may as well build the rig I want. Not comitted yet, but I am inching closer as I find parts. I figure I'll be no worse off than the guys that have gotten the Toyota Diesels and the trans requires fewer maint. items than an engine. I went all out when I did the motor on the idea it was a forever truck so this becomes a "why not". I dont care about a diesel like most on here, I dont want more power, I dont want huge tires and a foot and a half of lift, but I do want to row my own if possible.
Also, can anyone confirm those part numbers?

Like everything else in life, anything can be accomplished with enough time and money. I'm with Dan on this one. Not worth it. Also will be EXTREMELY difficult to get parts if you need them.

PM sent Landtank. And how much maintainence is a manual transmission going to need? I can order an extra clutch kit when I do the build. There are the hydraulics but worse case is I'll have to call in a favor from my Friend who is a Geologist in Sydney and park it for a month. Not sure what the cost is on the slave and master cylinder but I suppose I could stockpile one of those each as well. Beyond that I would just have to be really unlucky, which given all I've gone through with it so far is a distinct possibility I will grant you.
If you want to be your own parts department then you can more easily support downstream needs.
RHD stuff may not work on an LHD application however.

I have an interest in this as I've done a little ground work. As far as I can se the 80s don't have a pedal bucket like the earlier trucks but separate assemblies. I've been on the hunt for clutch and brake assemblies for a bit. Tapage has been on my list to contact for a while.
Dave Stedman can get this stuff pretty easily out of Japan.
I'll look him up. I've had this build in mind and very lazily been looking for the parts. These are the last of it to the point of looking for a good platform

Yes there is talk of the clutch pedal issue in some other thread. I don't think any of that stuff will be the dealbreaker here though. It is pretty easy to know going in I will need a pedal bucket or any of the other major components and not start until source them, relatively speaking of course. What worries me is the little stuff. There has to be a ton of small items that I would find I need as the build progresses. If that is a Japan only part then it has the potential to really drag this project out if I have to stop the build and wait for parts from Osaka 2 or 3 times during the project. I think that stuff will be more of a headache than maintaining it once I have it at steady state.
Pedal bucket would have to come out of Japan.
Also the clutch parts -- IIRC, clutch master and soft lines are available in the US. Hard line would be a Japan part (for the H151F).
HF2AV will not bolt up to the H55F. HF2A (from a 1991-1992 80 series) is the xfer one would need or, ideally, the PT xfer.
But as CDan said, be prepared for price shock and basiclly having your own parts dept for the long run.

And the RHD vs LHD could be an issue for sure. The shift lever itself has already been mentioned and I am sure it is far from the only part. Thats why I want to look at the diagrams and then start enquiring. Looking strictly realistically, a lot smarter people than myself have looked at this and not gone through with it. I still think it bears looking into though.
Also wonder about length and what not. Need to look at the driveshaft length and all that. I assume I am in for driveshaft mods but would be pleasantly suprised.
I see merits to the H55F and the H151F. The big selling point on the H55F would be that, at least in theory I would have to get less stuff from Japan...but probably have more custom stuff made due to the shifter and the lack of the H55F ever being offered in an 80.

The rig is driven very little, so I have lived with the low rpm bog... it will be good if the speed sensor is the problem.
The clutch pedal and bracket are separate from the brake. I modded a 89 - 95 mini truck bracket and pedal to work, it was fairly easy as far as fabbing things go.
I'll try to dig up the clutch info etc. and work on a flywheel solution.
The bell housing is available in the USA, I have one on the way.

So if I went with the H55F and sourced the Flywheel and Pedal from Japan, could the hydraulics and the clutch from a 60 be used? I dont know about it physically bolting up to the 1Fz flywheel and if the pilot bearing would work. I know an H42 has been installed in an 80 and the firewall had to be clearanced to get the shifter to work. I thought the H55 put the shifter in the same location so the mods to get it to fit should be similar. Then if I bolted an HF2A to it would I be able to utilize the stock 91-92 xfercase linkage to avoid fabbing shift linkage for the xfercase. Course as far as Fab stuff goes I dont imagine the shifter is a big deal and it is a trail that has been blazed so...
Also with respect to the shifter a friend of mine riged up a remote type shifter in an old Mustang when his trans swap put the shifter in the wrong location. It was a pretty simple device.

Devil's advocate here.
What is the genuine benefit to the conversion?
Agreed a manual trans can be fun, my STR8 Challenger is a 6 speed. Automatics are much better off road and I have never had issues towing fairly large trailers.

I dont guess there is a real benefit. Perhaps that 1MPG on fuel economy and winning the Internets but other than that it would strictly be a preference thing. I do appreciate the devils advocate bit though. FWIW my auto didn't like towing a modest Pop Up camper...It would slip pretty good in 4th even on the flat highway. I would end up just turning OD off. I expected this in Western NC...not so much in central Florida though.
One other question...Is the vacuum actuated Tcase in the 62 models the same as the 60 trucks with the exception of how the 4WD is engaged? If so I would think maybe I could get it to work with the HF2AV shifter and use the CDL button to actuate the 4WD. That would simplify that if I went with the H55.
Also anyone know what the lenght difference is on the H42 vs the H55? I could prove the concept with the H42 and if it was good to go bolt in the H55 if it didnt require further driveline mods and not be too invested in the whole affair if it all went south since H42s can be scored cheap assuming the bellhousing I was looking at will work with either trans. Ideally though I'd just assume keep the full time though as I think it will simplify this.

later H42's have a spacer on the rear of them that make them the same length as the h55.
The split case is different than the hf2av since it is built onto the back of the transmission. The hf2av is a sealed unit. I have wondered if the output shaft on the h42/h55 could be cut down and used with the hf2av though - If you had them on a bench side by side it would be pretty easy to figure out.
The 60 clutch pedal bucket will not work, I tried and it was too flimsy once it was cut down and modded. I have a simple pattern saved that I have used to make a couple of pedal buckets if you or anyone else wants it. It is pretty simple to build really:
