Hi all! Looking for some assistance/advice for doing the washer mod on the rear axle of my LJ78 Prado to correct the pinion angle. My rear driveshaft angles are out of whack after an engine swap, transmission modification and lift and are causing bad vibrations and eating the rearmost u-joint. If anyone has done this modification for caster correction and would be willing to lend a hand or give some useful tips on how to go about it that would be fantastic!
