Wanted 2000 up 100 series front diff

[brew]

I chewed up the spider gears in my 98 lx470 and would like to repair it with the 2000 up 4 pin setup. I think a late 99 will have it also. I'm willing to buy a complete diff or just the parts to upgrade it - spider gears, pins, etc. I know shipping will be much easier for the parts but I'll have to do research to make sure I get all the parts I need to upgrade it. thanks a lot.
