I have been following the options for making a soft top for a few years. Ehsan is still in the buisness of making tops, but does not have the pattern for a FJ25. I don't know anything about the OCD tops or the Badger tops.
I wish Dave (cruiserloser) would chime in. We have traded a few emails about the possibility of one of his canvas guys making a top or 10.
The metal around the windows can be made by most sheet metal shops, and I would be happy to send my top to someone who could make a copy.
I too thought about making only the top, without the sides or back. It would be perfect for 90 % of my wheeling. But, "In for a penny in for a pound."

Ehsan was contacted many years ago about this. If he had shown more interest I considered getting the section from the A pillar to the B pillar and ship it to him. At that time I knew of a early soft top tub in a junk yard. If you read thru this thread you will see most mudders probably wouldn't trust buying a special top from him.
https://forum.ih8mud.com/fj45-classifieds-corner/141615-project-hub-cap-pakistan.html I had a few emails with him about the hub caps but didn't like the idea of a direct bank deposit so didn't get involved.
Badger was the first attempt. They make high end Rover tops in MA. Price is $3K a copy and not sure if it includes canvas for the doors. But it didn't include making new skins for the doors which is more complicated then the later doors.
OCD made one top to get a pattern with the idea of being able to make tops for the rest of us. Just about this time his wife left him and everything changed. A few threads about it. If they are still around they will be in chit chat section. OCD has been banned from mud.
There was a rumor of someone getting his equipment and patterns. But at this time if it happens I'm not holding my breath that it will include the early soft top.
I was also in contact with Abe in CO who is currently bringing FJ40 tops from out of the country. At that time he was planning on making top locally and would be willing to make the a batch of early tops. If need be I would have transported a early tub and bows to make it happen. The contacts he had weren't really interested and since he was already setup to import he went that route. Again the issue of no tub and bows to work with.
This top showed up a couple of years of ago
https://forum.ih8mud.com/40-55-series-tech/534141-my-friend-mexican-fj40-61-62-a.html I believe a member here was in contact about getting it made in Mexico. This was going to be with some mods to make it more correct. I haven't heard anymore and I don't believe he did either.
It has been said that making Land Cruiser tops carrys a curse. Besides OCD another guy back east trying to make Fj40 tops died. Every attempt to make a batch of early tops has failed. Most FJ40 tops have had there share if issues. Even Specialty Tops that took over for Kayline went belly up. I can see this might be going the same way with a difference option on how to handle this. Instead of getting into a debate of who is best qualified to get this done I have a honey do list a mile long and will gladly back out now.
As for just having a top with no sides guessing anything made to fit the later factory bows should be really close. Maybe a little adjustment. It is a little narrower but biggest different is the location of B pillar and the shape of the door. Those are a non issue when not dealing with the sides. A few years back I bought a bikini top from Alex (southbostonfj40?) who was handling paki items shipped here by Ehsan. The top is designed to fit the factory FJ40 bows. Never tried it on my early bows. I've stored it out of town. Picked up another set of early bows last year so I'll bring it back and take a few pictures of how it fit the early tub A to B pillars. The length front to back is the same or real close. So if it fits the front part should be okay from there back. Another cheap option would be to use a cheap used top to make one. At some point that's what I might do with this top.
