just in case anyone cares. I think I might have found a potential solution to this.

Since the crooked seat angle applies to the driver side seat. I.e. In USA LHD driver seat is crooked, and in other parts of the world RHD driver seat is crooked, I am going to order the passenger side seat frame of a RHD vehicle to swap into my LHD driver seat. Per real oem, they are different part numbers which may solve for the crooked seat issue.

If that doesn't work, I also manage to find a junk set of driver side seat rails. I am going to try to widen/elongate the holes at the rail to give more degrees of freedom to angle the seat dead center. Then I'll clamp down the seats with larger washers.

stay tuned for pics!
