1hdfte engine to nissan patrol gearbox spigot bearing for back of crank on fte engine, patrol spigot is a odd size 15.8mm less than 5/8 some companies use a 40x16x12 and its way to big on the id and will damage your input shaft and input bearing create clutch noise and wont last. this bearing of mine is a nice fit and a super high quality japanese bearing for $165 including express post, These are not standard bearings these are special large bore id and are not cheap ,plus to precisely machine them takes time to get it right. all now are cnc made
