I doubt you will find anything in this country. What your trying to do is something I've never seen come in to this country or at least not this early which is mount hard doors with soft top bows. FJ25s and early FJ40s thru 63 used a completely different soft top setup. Sometime in 65 the windshield and doors changed. The angle on the side of the windshield changed and the hard top doors got shorter. After that time the soft top and hard top doors fit the same opening. I'm not sure what the bows were like for the 64 and 65 model but I think it's probably pretty close to what you have now for the piece over the door. The weather stripping for the soft doors fit in a track along the outside of the door while the hard doors was glued along the inside edge. I know the piece above the doors for the FJ25s and early FJ40s was thicker like the later ones just shorter. This makes me think the 64 and 65 soft top bows piece were thick too.
Here's two things you can do.
1. Run soft top doors from a later FJ40. The front edge will be off a little but the soft top door should be able to bend that much. I have a 63 hard top I got sitting around and right now I got soft top doors to keep it closed up. The doors are a little short.
2. Find the pieces from above the door on a early hard top and add the channel for the canvas to go thru. Then figure out how to attach it to the B pillar bow.
