The 24 million dollar question is how much to replicate the top plate for us mere mortals?
40 series 5 speed. (1 Viewer)

My understanding is that the latest of non USA 40s had the 5-speed, but it had a different top plate to accommodate the transmission hump? You can get a new H55 transmission for a 60-Series, 70-Series, but it won't fit the more forward hole of the 40 transmission hump. Here, is a proper casting for the 40 series top plate.
An H55 would be ideal for a crawler first gear, and freeway, but you are going to need to move the frame crossmember on a 40 a bit back? That, and adapt whatever is necessary for shifting on a split case, the necessary changes in driveshafts, and the handbrake.

It's more so that the last of the 40 series had a different transmission tunnel / hump to accommodate the 5 speed.
Earlier 40's can be fitted with 5 speeds without too much trouble by clever use of mixing and matching cross members and mounts to gain more trans tunnel clearance.

Can use the same belling housing and clutch as long as the H55F input shaft is correct. A H55F made after 10/85 will require grinding a few spots on the bellhousing to clear the oil channels on the input bearing retainer. But that would be on all F/2F bellhousings. The 3F bellhousing has the clearance but rotates the transmission which creates other issues.
Having the holes for the motor mounts should not be a issue. Will end up needing one side to mount the clutch slave cylinder. While not recommend some has used the old motor mounts with a five speed.

I'd like to see a better first post by the OP with an explanation of exactly what is going on here. I have a H55F in my FJ62 and would never have one without that setup. I have a 77' FJ40 US model that I would kill to have a 5 speed in. I have found no threads on MUD for my vintage with an H55F swap. I see Poser's later unit and a couple of 75' and earlier.
If this transmission gets me the gearing of an H55F in my 40 I'm in without reservation. If I have to swap the rear axle to get a parking brake I'll do it. What range of year models will this unit go in and what is required? If it is a commercial product I'd like to see write ups on parts lists needed for the different year trucks and what other requirements such as parking brake options, cross members, bell housing, split T-case etc.
When I swapped the H55F in my FJ62 there were zero threads on MUD from anyone on doing this. If I'm laying out cash for this unit I want to know how to make it fit in my 40. I really appreciate the effort to make this transmission and don't mind paying for the R&D that goes into it.

My apologies for any confusion!....The topic of the thread only relates to the reproduction of the Landcruiser 40 series 5 speed top cover to suit Toyota H55F transmissions.... The transmission in the pics is obviously a H55F though is only included to demonstrate the function of the reproduction top.

Whoa. Easy. The first thread is pretty clear. He’s the first one to reproduce a 40 series top cover for an h55f. He hasn’t even brought it to market yet. Besides, this probably isn’t a swap for a guy who needs step by step directions.

As @Living in the Past noted above (Post #20), the split transfer case can be easily fitted with an OEM drum parking brake. For my '71 FJ40 I ended up buying an entire split transfer case here on MUD (from a BJ45) that came from Toyota with a parking brake. Georg @orangefj45 should have the parking brake conversion parts in stock.

And yes, I have a a few of the OEM e-brake setups in stock along with the rebuild kits.

Impressive indeed. 
My guess is 5 people actually have the money to buy one when it becomes available and the rest will complain it’s too expensive... even though it’s pretty much one of the holiest of grails in the LC world.

If I may. Buy a new H55F for a 60 and this new top. You will save time and money as well as have a new assembly. I paid $1400.00 for a used H55f and TC out of a BJ from northern Europe. Plus shipping from the midwest where I located it. I then had to purchase a new input shaft and bearing retainer. By the time I have it all rebuilt and account for the transmission crossmember, parking brake, new shifters, new access cover, new driveshafts, etc, etc. etc. I imagine I will have close to 6k in a USED H55F and TC. Yes it will be the H55F with a 40 series top that I wanted. But if the repro 40 top had been available that is the route I would have gone. My impatience has once again cost me dollars.
