If you are sick of blowing 8" toyota centres we have a great solution for you.
This adaptor ring can be bolted to your housing, welded in place and then after alot of grinding and fitting a new diff cover you can bolt in a nissan patrol centre (hi or low pinion type)
You will need to fit a locker and swap the spider gears out for some to suit toyota axle splines, then simply refit your current axles etc.
Note* there is a bit of work in this and may not suit everyone, if you already have a bit of money in your front end and it all fits well this may work for you. Lots of welding and grinding involved.
See it fitted here
