i bought a lockrite LR1610 for my 1986 toyota pickup DLX long bed 4x4 22r. the box says it has 30 splines and i’m not sure if my rear axle has 30 or 27. i’m going to have the locker installed at the same time i drop off the diff and third member to get re-geared, but i don’t want to leave with with a wrong part.
