the sm 420/465 have super low gears and mount up to a 4.3 chevy
they have a 23 spline output
toyota tcases have a 23 spline and i already have twins
i'm puting a 4.3 in my crawler and want to make my rear end gears stronger by getin 4.88s(now rining 5.29s
thats why + a sm420/465 is stronger than a g52/w56/r151
