hi, the tunnel on right side might need to be cut out some, depends. the jerico is square on top. the shifter can come through same hole, depends on shifter used. the long shifter will require a bigger hole.
you do not lift , shifting these trans. you can lift some and double clutch if driving easy. on full throttle , toe tap the clutch pedal, and pull handle. the trans requires a clutch to come out of gear, not going into gear. you have to fabricate a trans mount to fit, change front yoke to a turbo 400(, 1350 joint), which means a drive shaft
I shift mine foot on the floor , it shifts faster than a mopar trans.
its worth the effort!! jerico is lot stronger.
