Just removed mine today to inspect the clutch and it took a good 3-4 hours but im no mechanic lol
had to disconnect starter motor, what a bitch the top bolt is
Cluch slave cylinder
front exhaust
cross member
brackets that held rear of gearbox
Bell housing bolts again the top ones were a bitch
Electrics from top of gearbox
Gear lever and Hi/Low lever...this meant most of centre dash had to come out to get to bolts holding hi/lo lever
Im sure there was more but me heads done in and cant remember it all.
Not sure what else you need for the oil seal...good luck.
