Just incase anyone is interested in what a locking differential from a T25 syncro looks like. They can be made to fit a 6 rib 091 code bay gearbox with a little machining or a mounting block for the solenoid. I'm not sure if it will also fit a 002 3 or 5 rib box but a few people in the US say it can but they'v never seen or done it. The parts diagram: The vacuum system: Blue thing is the actuating solenoid: Heres the stock differential in 091 box as a comparison: Parts diagram: Video of how diff lock works: Syncro rear diff lock operation
Indeed it would Mb dude Im thinking if a stock height bay with all terrain tyres and locking diff cant manage the terrain then im asking too much of the design It will be far more capable than all the mitsubishi pick ups and range rovers that keep getting stuck round here
