If your going to use the wheel hubs from an ifs toy, what should it matter if the lockouts are manual or auto? Your gonna need the corresponding solid axle lockout hubs, for the spline count to be appropriate for your birfields. The ifs lockouts may work but you will need to get some 30 spline hub gears for them from Bobby Long @ toyotasuperaxles.com .
I realize i would use the lockouts from the solid axle I guess my question should have been, Do the solid axle lockouts bolt on to the ifs hubs that have the auto lockouts?
