The original 80 Series sector shaft is a bit weak for extreme use.
So when it is time to rebuild your steering box, upgrade to the beefier 105 sector shaft that is 10% larger in diameter and will be significantly stronger than the old unit.
THIS KIT IS FOR LEFT HAND DRIVE VEHICLES ONLY
Professional installation is required.
( note: on the last picture with the 80 series spline twisting due to steering stress )
