1999 Patrol GU Y61 Diffs

[Engism]

I will n get back to you ... other forums point to 9 bolt is pre 90 and 11 bolt post 90 .... mines 1999 but others say H233 is 11 only .... whats frustrating is I am in the very north of Thailand at the moment ... will get a mate to check the housing bolts
thks for your time

I think i have been led down the garden path by looking too deep ..... seems there are a differing number of mount bolt on the diff centres but all crown gears have 9 holes and it was the crown gear mounting holes i was in need of knowing.
Thx for your time and hopefully my theory is right but I have still to physically confirm it ... wish me luck.
