Lang,
Looks like you had a real win with that 420/465 box!
They are highly sought after still to this day, can pump insane amounts of HP into them without breaking them!
Got a cupla books here somewhere where the seppos were fitting them to jeeps and blazers etc behind 600 odd horses!
Still scratching my head over those so called professionals modified the driveline and set the axle back, though!
Like something I'd do!
No doubt you'll nut it out!
Cheers, Dave64
