When installing a non-ABS R200 diff into a RWD Nissan S or R (Silvia / Skyline) body that originally had ABS you will find the diff is no longer the correct length to match the propshaft. The 18mm Garage-D propshaft spacer will solve this issue.
Kit includes necessary longer bolts and matching nuts.
Both the spacer and the fixings are anodised to prevent corrosion.
