I have 2 used OEM posi units for sale. These are for the 8.5" 10 bolt BOP rears. One is cone style. I have disassembled it and inspected to be sure the cones have not bottomed out. This is a series 2 unit ( 2.56 ratio and numerically lower), which can be used with a gear spacer to mount 2.73 and numerically larger gearsets. The second one is a #726 S spring style clutch plate unit. #726 is a series 2 BOP unit that will not work on C clip style axles. Bolt in axleshafts only. Used with a ring gear spacer this unit can be used to install 2.73 and numerically larger gearsets Used good condition. No warranty. $99 apiece plus shipping in the USA.
