    u will need the correct adapter & output shaft for the t-400. your tranny shifter should work, u will just not line up w/ what the dash says, u will need the t-case shifter & linkage, a torque converter, & possibly new d-shafts. if u want a kickdown u will have to mount a switch under the gas pedal & run some wires for it.:D
