I like it too, I compared the stock Subaru rear diff to the 720 front diff they both have the same mounting and same driveline flange , so the 720 diff will bolt right into the soob with no mods to the mounts, also the 720 front axles are different lengths ones about 4" shorter then the other, also the hub to hub measurment on the 720 Nissan truck is around 5-6" narrower, so if I get a second long axle and put in on then both axles will be same length and it will bring the track out close to the soob track width, so looks like I need to pull apart a sooob rear arm and a nissan front hub arm and see if it fits if not then make a custom arm with the truck bearing holder hooked to the soob arm , if this all works out I will have a stronger rear drive system and unlocking rear hubs and 6 bolt hubs with big disc brakes
heres a pic I found its like the one on the left
