I need to replace an EZ Locker that was installed in my 1973 FJ40. Should I replace with OEM or is there a good quality aftermarket setup of Spider gears, shaft and side gears?

Okay, this is what I found out. I need fine spline for the axles and course spline for the pinion gears. Toyota went to fine spline axles in 68 and moved to fine spline pinion in 78. Ee
The ones in the circle should be the correct ones.

Believe by 69 they were fine spline. This was when Toyota was making changes all the time. I know the there are a few fine spline ball and claw axles out there but never heard of a coarse spline Birfield axle. To my knowledge only Lock-Right was made for coarse spline in this style locker. Torsen was as well but would need a whole carrier for those.
