This was a 3:45 open diff that has had the posi unit from a 3:07 put into it using the 3:45 gear set.. The conversion was done by the Gear Shop in Phoenix. The whole unit was inspected and hot tanked. All of the bearings and seals did not need replacing. The bearings are tight and the seals are soft and pliable. The lash has also been set. The unit has had the Euro vapor recovery tank added .
$1700 plus shipping which should be about $125 in the lower 48
